Performance of CsPbBr3 Quantum Dots Passivated by Dual Ligands and Their Light-emitting Diodes 增强出版 AI导读
“CsPbBr3量子点在QLEDs领域展现巨大潜力，采用DDAB与DOTA联合钝化策略，有效提高量子点发光性能，制备的QLEDs器件亮度和外量子效率显著提升。”摘要：CsPbBr3 quantum dots （QDs） have demonstrated great potential in the field of QLEDs due to their high photoluminescence quantum yield and narrow-band emission characteristics. However， CsPbBr3 QDs surface suffers from a significant number of Br vacancies and under-coordinated Pb2+ ions， which introduce trap states within the energy band， promoting non-radiative carrier recombination and reducing device efficiency. In this study， a dual-passivation strategy employing DDAB and DOTA was implemented. Through their synergistic effect， this strategy effectively fills surface Br vacancies and coordinates with exposed Pb2+ ions， thereby reducing surface defects and enhancing the luminescence performance of the QDs. Through TEM， XRD， and FT-IR analyses， it is demonstrated that the photoluminescence quantum yield （PLQY） of quantum dots treated was increased to 99.65%， along with enhanced thermal stability and film-forming ability. The fabricated QLEDs devices achieved a maximum brightness of 8 000 cd·m-2 and a peak external quantum efficiency of 5.29%， which is 1.48 times that of QLEDs devices based on unpassivated QDs.关键词：perovskite;quantum dots;joint passivation;surface defects265|42|0更新时间：2025-12-25

- 摘要：Fine tailoring the shape of nanosheets is still a big challenge as the difficult synthesis for highly controlled ultrathin nanosheets. Here we report a facile strategy for tailoring the shape of ultra-thin NdF3 nanosheets via a hot injection method. In this method， NdF3 nanosheets with only about 2 nm in thickness synthesized first via a hot injection method. The shape of the NdF3 nanosheets was able to be tailored from flower-like to the round or the triangular shapes simply by decreasing the reaction temperature from 300 ℃ to 280 ℃ or 260 ℃. The driven force of the NdF3 nanosheets’ shape tailoring by the temperature could be that a lower crystal growth rate will guarantee the more stable facets exposed at lower temperature， while under the condition of slow precursor injection， a higher temperature will lead to a further decrease in the crystal growth rate. This shape control method of NdF3 nanosheets is highly robust， which could be promoted to other materials.关键词：Nanosheets;NdF3;shape tailoring;Rare-earth Fluorides64|63|0更新时间：2025-12-25

However， at present， the short-wave infrared phosphors doped with Yb3+ ions still have some defects such as inability to be excited by blue light， low quantum efficiency and narrow half peak width， which affect their further application in the field of short-wave infrared spectroscopy technology. In this paper， a Ca2NaSb2Al3O12∶Cr3+，Yb3+ phosphor with broadband and efficient short-wave infrared emission is reported. The phosphor can exhibit efficient photoluminescence in the range of 640-1 150 nm under the excitation of 460 nm blue light. In Ca2NaSb2Al3O12∶Cr3+，Yb3+ phosphors， with the adjustment of Yb3+ ions， the infrared emission intensity of the phosphor is increased by 2.7 times， and the emission spectrum is broadened from 640-900 nm to 1 150 nm. By testing the quantum efficiency of the sample， it is found that the internal quantum efficiency is as high as 85.56%. Moreover， the sample also has excellent thermal stability， which can maintain 82.0% room temperature luminous intensity at 250 ℃. By combining optimized phosphors with a blue light 460 nm LED chip， the SWIR pc-LED device achieved a maximum output power of 101.5 mW at a driving current of 350 mA， with a photoelectric conversion efficiency of 8.86%. It has potential applications in non-destructive internal detection and biological imaging.关键词：Short wave infrared phosphors;Cr3+ and Yb3+ co-doping;energy transfer118|54|0更新时间：2025-12-25
- “在发光二极管领域，研究人员采用高温固相法制备了Hf1-xTe3O8∶xCr3+长波宽带近红外荧光粉，为夜视、生物医学成像等应用提供新方案。”摘要：Near-infrared phosphor-converted light-emitting diodes （NIR pc-LEDs） are promising candidates for compact NIR light sources. However， their development is hindered by the scarcity of long wavelength and broadband NIR phosphors. In this work， a series of long wavelength and broadband NIR phosphors， Hf1-xTe3O8（HTO）∶xCr3+（x=0-0.15） were successfully synthesized. The crystal structure and photoluminescence properties were system-atically investigated. Under 450 nm excitation， HTO∶Cr3+ phosphor exhibits a long wavelength and broadband NIR emission peaking at 865 nm with a full width at half maximum of 167 nm （2 149 cm-1）. Crystal field strength calculations reveal that the NIR emission is attributed to Cr3+ ions occupying a single crystallographic site of Hf4+ within weak crystal field environment （Dq/B=1.97） in HTO. Moreover， an NIR pc-LED device was fabricated by combining the optimized HTO∶Cr3+ phosphor with a blue LED chip. The application experiments also demonstrate that HTO∶Cr3+ has potential in night vision and biomedical imaging applications.关键词：Cr3+ doping;HfTe3O8;Near-infrared phosphor;broadband;single-site occupancy125|35|0更新时间：2025-12-25
- 摘要：Theoretically， blue phosphorescent materials are capable of achieving 100% internal quantum efficiency. Nevertheless， the mutual constraints among efficiency， color purity， and stability remain one of the key bottlenecks in the industrialization of organic light-emitting diodes （OLEDs）. In addition， the design and application of host materials also exert a significant impact on the overall performance of blue light-emitting devices. To address this issue， this study constructs a series of host materials with high triplet energy levels by designing different connection modes， based on 9-phenylcarbazole and benzimidazole units. Through a combination of theoretical and experimental approaches， the correlation between the chemical structure and performance has been unraveled. It is found that the designed and synthesized blue phosphorescent bipolar host materials based on different biphenyl linking sites， i.e.， 9-（3'-（1-phenyl-1H-benzo［d］imidazol-2-yl）-［1，1'-biphenyl］-3-yl）-9H-carbazole（mCzmBI）， 9-（2'-（1-phenyl-1H-benzo［d］imidazol-2-yl）-［1，1'-biphenyl］-3-yl）- 9H-carbazole（mCzoBI） and 9-（3'-（1-phenyl-1H-benzo［d］imidazol-2-yl）-［1，1'-biphenyl］-2-yl）-9H-carbazole（oCzmBI）. The three compounds have a similar triplet energy level of 2.70 eV， accompanied with the glass transition temperatures of 92 ℃， 103 ℃， and 93 ℃ respectively. mCzmBI， mCzoBI and oCzmBI are regioisomers， but differ in the linking sites of carbazole and benzimidazole on the biphenyl linker. This difference in linking positions enables effective regulation of the host materials’ properties. Constructed with the blue phosphorescent material bis（4，6-difluorophenylpyridinato-N，C2）picolinatoiridium（Ⅲ） （FIrpic） as the guest， the influence of the three hosts on device performance is clarified. Overall， the device using mCzmBI， a host linked by biphenyl at double meta-positions， achieved a maximum current efficiency of 24.9 cd·A-1 and a maximum external quantum efficiency exceeding 12.8%， it also demonstrates low efficiency roll-off under high-brightness conditions. This work offers an effective strategy to the development of high-efficiency blue phosphorescent hosts.关键词：Blue phosphorescent;Organic electroluminescence;9-phenylcarbazole;Benzimidazole;Host materials66|43|0更新时间：2025-12-25
- 摘要：The wide band gap characteristics of gallium oxide make it very suitable for the preparation of solar-blind ultraviolet photodetectors. The responsivity of ultraviolet photodetectors based on thin films is often low. However， nanomaterials have excellent photoelectric properties in device applications due to the high stability brought by high specific surface area and high crystal quality. Here， we successfully deposited β-Ga2O3 nanopores on the double-pass ordered porous AAO template by PLD. The porous AAO template is used as the growth space of nanomaterials， and the gallium oxide material is filled into the pores of the template to form a nanotube structure. By optimizing the preparation process， the relationship between the performance of gallium oxide nanopores and the growth time was studied in depth. With the increase of growth time， the responsivity of the detector was improved. The rise time τr=0.7 s， the decay time τd=1.3 s， and the responsivity reached 4.63 mA·W-1 ， which was higher than 2.24 mA·W-1 of the responsivity of silicon-based gallium oxide nanorods.关键词：β-Ga2O3 nanopores;AAO template;PLD;wide bandgap semiconductor materials52|40|0更新时间：2025-12-25
- “在激光晶体材料领域，研究人员通过多种技术手段验证了氧化镥晶体中的小角晶界缺陷，为优化晶体生长工艺、提升晶体性能提供理论指导。”摘要：As a highly promising laser crystal material， lutetium oxide （Lu2O3） exhibits remarkable advantages in laser applications due to its high thermal conductivity， low phonon energy， and strong crystal field effects. However， its extremely high melting point （2 450 ℃） poses significant challenges in maintaining a stable thermal gradient during crystal growth， leading to issues such as temperature inhomogeneity and thermal stress accumulation. These factors can trigger a sharp increase in crystal defects， severely compromising crystal quality. In this study， small-angle grain boundary defects in Lu2O3 crystals were identified using focused ion beam-scanning electron microscopy （FIB-SEM） and transmission electron microscopy （TEM）. The influence of small-angle grain boundaries on crystal quality was characterized through high-resolution X-ray diffraction （HR-XRD） and Laue diffraction. Furthermore， the origins of dislocation etch pits near grain boundaries were investigated via high-angle annular dark-field scanning transmission electron microscopy （HAADF-STEM） and inverse Fourier transform analysis. These findings provide theoretical guidance for optimizing crystal growth processes and enhancing crystal performance.关键词：Lu2O3 crystal;small-angle grain boundary;rocking curve;dislocation defects99|95|0更新时间：2025-12-25

- “透明OLED研究取得新进展，通过优化电极和传输层，实现了低电压高亮度双面出光。”摘要：Transparent OLEDs have the characteristic of double-sided light emission and have broad application prospects in fields such as head-up displays and wearable devices. In this paper， a Mg∶Ag transparent electrode is first designed. By reducing the thickness of the thin film and regulating the doping ratio of Mg in Ag， the light transmittance is improved. It is found that when the thickness of the Mg∶Ag film is 14 nm and the doping ratio is 1∶1， the transmittance of the electrode is 60%， and it also exhibits the best comprehensive performance in the forward OLED device. Subsequently， combined with the optimized Mg∶Ag transparent electrode， the hole and electron transport layers are optimized in the inverted device. Finally， in the inverted device， the performance of the device is further improved by evaporating a BCP light extraction layer on the outer side of the Mg∶Ag cathode. The results show that when an N-type electron injection layer with a thickness of 60 nm and a doping ratio of Bphen∶Cs₂CO₃ of 1∶1， a hole injection layer of HAT-CN with a thickness of 40 nm， and a BCP light extraction layer with a thickness of 50 nm are used， the turn-on voltage of the OLED device drops to 2.4 V， the maximum current efficiency of the device is 43.1 cd·A-1. Under the driving of a current density of 10 mA·cm-²， the light emission brightness on both sides of the OLED device is 2 237 cd·m-² and 1 844 cd·m-² respectively， the ratio of the luminous intensity on both sides is 45%∶55%， and the light transmittance of the device at 530 nm may reach 82.0%.关键词：transparent OLED;transparent metal electrode;inverted OLED176|150|0更新时间：2025-12-25

Regulating Phase Distribution of Quasi-two-dimensional Perovskites for Blue Light-emitting Diodes 增强出版 AI导读
“最新研究突破了准二维钙钛矿发光二极管性能瓶颈，为高效稳定蓝光器件提供新方案。”摘要：Quasi-two-dimensional perovskites have been used to construct high-efficiency perovskite light-emitting diodes （PeLEDs） due to their multi-quantum well structure， cascade energy transfer and high luminescence quantum efficiency， which have broad application prospects in the fields of display and lighting. Due to the non radiative recombination caused by a large number of small n-phases in quasi-two-dimensional perovskite， blue light PeLEDs face problems such as low energy transfer efficiency and unstable emission spectra， and their performance lags behind red and green light devices. This article introduces poly （4-styrenesulfonic acid sodium） and cesium chloride to the hole transport layer to synergistically regulate the crystallization of perovskite thin films by affecting the nucleation and growth process of perovskite. The phase distribution is controlled， effectively suppressing the small n-phase components in perovskite and improving energy transfer efficiency， and reducing the trap state density. As a result， non radiative recombination is significantly suppressed. In addition， chloride ions diffuse into the perovskite layer and tune the blue emission of the thin film through ion exchange. The optimized blue PeLED device has an emission spectrum located at 488 nm， a maximum brightness of 2 772 cd/m2， and a maximum external quantum efficiency of 4.9%. This work provides an effective method for achieving efficient and spectral stable blue PeLED.关键词：Blue perovskite light-emitting diodes;quasi-two-dimensional perovskite;Phase distribution regulation;hole transport layer110|35|0更新时间：2025-12-25 - “在有机发光二极管领域，研究者采用p型掺杂层PEDOT∶PSS，发现漏电流影响器件性能，为高亮度应用提供见解。”摘要：OLEDs have been prepared using a p-doped layer poly（3，4-ethylenedioxythiophene）∶poly（styrene sulfonate） （PEDOT∶PSS） for hole injection， whereby the effects of leakage （electron） current on the PEDOT∶PSS and device performances have been investigated. It is found that some injected electrons leak into PEDOT∶PSS via the shunt paths formed due to the inevitable cathode diffusion through device， reducing PEDOT cations to neutral PEDOT molecules. This markedly decreases the conductivity of PEDOT∶PSS， causing the saturations and even degradations of the current density and luminance of devices at high driving voltage. Increasing the thickness of either emissive or electron-blocking layer， using the smoother-surface electron-blocking layer and adopting n-doped electron transport layer all help suppress the diffusion of metal atoms and decrease the formation of parallel paths， which will alleviate the electron leakage and thereby increase the width of exciton formation zone and the device stability. The current research provides some useful and practical insights into the development of p-i-n organic light-emitting diodes towards high-luminance applications， such as electrically pumped organic lasers and microdisplays.关键词：organic light-emitting diodes;electron leakage;conductivity decrease;p-doped hole transport layer;device performance;stability131|92|0更新时间：2025-12-25

In the design， the reflective semiconductor optical amplifier （RSOA） is hybrid integrated with a silicon-based nanobeam cavity through butt-coupling method. The nanobeam cavity has a high quality factor， small mode volume and compact footprint. It is the critical passive device to build the narrow-linewidth tunable waveguide-based ECDL. We build a comprehensive simulation model to analyze the optoelectronic response of the waveguide-based ECDL with a nanobeam cavity. The spot size converter （SSC） is optimized to achieve highly efficient butt-coupling between the RSOA and the single-mode silicon channel waveguide. And the influences of the insertion loss of the SSC and the reflectivity of the nanobeam cavity on the performance of the ECDL are discussed. By changing the refractive index of the environment in which the nanobeam cavity is placed in the simulation， we can tune the wavelength of the ECDL efficiently at a sensitivity of 120 nm/RIU. The size of the nanobeam in the designed ECDL is only 0.7 μm×20 μm and the simulated linewidth is 30 kHz.关键词：external cavity diode laser （ECDL）;nanobeam;silicon photonics;hybrid integration187|139|0更新时间：2025-12-25

“最新研究报道，采用改进水热法制备了不同Er3+浓度掺杂的LiYbF4上转换纳米发光材料，系统表征了其微观形貌、晶型结构、上转换发射光谱和上转换荧光温度传感特性。”摘要：A series of LiYbF4∶Er3+ upconversion nanocrystals were fabricated by an improved hydrothermal method. The morphology， crystal phase， upconversion luminescence （UCL） properties and its temperature sensing performances of these synthesized nanocrystals were systematically demonstrated and discussed. The scanning electron microscopy （SEM） results show that the particle size varies from several hundreds of nanometers to several micrometers with different doping Er3+concentrations. The X-ray diffraction （XRD） patterns display that the XRD peak remains basically unchanged with the increase of the doping Er3+ ions， indicating that the introduction of Er3+ does not change the crystal phase of the LiYbF4 hosts. Under the excitation of 980 nm continuous-wave laser， the LiYbF4∶x%Er3+ nanocrystals achieve the strongest UCL intensity when the doping Er3+ concentration（mole fraction） is fixed at 0.05%. The further UCL temperature-dependent measurement reveals that the quenching temperature of the UCL reached ~600 K. The UCL temperature sensing properties of these highly thermally stable nanoparticles were further investigated over a wide temperature range of 298 K to 623 K. The results show that the maximum relative sensitivity （Sr） at 298 K is 1.296%·K-1， and the temperature uncertainty （δT） is less than 3.1 K under the measured temperature， and δT<0.266 K when the temperature is lower than 573 K.关键词：upconversion luminescence;temperature sensing;LiYbF4∶Er3+;nanocrystals;hydrothermal method225|55|0更新时间：2025-12-25 - “在化学传感领域，研究人员开发了新型荧光探针NAM，实现了对Zn2+的高选择性响应和快速可视化检测。”摘要：A novel fluorescent probe NAM was synthesized via a condensation reaction employing 3-formyl-4-hydroxy-N-butyl-1，8-naphthalimide and 4-aminoantipyrine as raw materials.

However， excessive usage of N2H4 and ClO- poses a grave threat to the environment， ecosystems， and human health. To evaluate the environmental hazards caused by N2H4 and ClO-， there is an urgent need for efficient approaches that can achieve rapid and precise detection of N₂H₄ and ClO-. Here， we report a novel dual-responsive colorimetric/fluorescent probe， named 5-（（6-（dimethylamino）naphthalen-2-yl）methylene）-1，3-diethyl-2-thioxodihydropyrimidine-4，6（1H，5H）-dione （NSE）， capable of detecting N2H4 and ClO⁻ in environmental， food， and biological samples.

In practical applications， NSE has been employed to detect N2H4 and ClO- in various samples. Portable detection tools loaded with NSE， including cotton swabs， test strips， cotton-thread patterns， enable intuitive and real-time detection of N2H4 and ClO-. Moreover， NSE can also be utilized for imaging N₂H₄ and ClO- in cells， Arabidopsis thaliana roots， and onion epidermal cells.
