However， it is still challenging for organic emitters that exhibited intense red emission with a maximum emission （λem） above 680 nm in solid state. In this work， two D'-A-D-A-D' molecules with a benzodithiophene derivative core donor （D）， a benzothiadiazole acceptor （A） and a N-phenyl-2-naphthylamine derivative peripheral electron donor （D'） but differing in fluorine-free D'（RH） and fluorinated D'（RF） were synthesized. Their chemical structures were characterized and confirmed by nuclear magnetic resonance spectroscopy and mass spectroscopy. It is found both of them presented λem> 700 nm in solid films. Meanwhile， RF showed a more pronounced aggregation-induced emission enhancement effect and a higher photoluminescence quantum yield than those of RH， attributed to the fluorination induced a larger dipole moment and more twisted structure of RF. LED devices based on RH and RF doped PMMA as colour conversion layers were fabricated， respectively. The maximum brightness of RF based device reaches 2.5-fold of RH based device at a 3.8 V work voltage， and its CIE coordinates （0.70， 0.27） close to standard red light of BT.2020 color gamut. This work provides a promising way for developing organic red emitters with higher brightness and colour-purity.关键词：Organic red emitters;Benzodithiophene;Fluorination;Red light color purity;red LED92|61|0更新时间：2025-09-17

- “在可拉伸光电器件领域，有机半导体材料研究取得显著进展，为推动其发展提供新思路。”摘要：With the rapid development of stretchable and wearable electronic devices， organic semiconductors have attracted much attention in the research field of stretchable optoelectronic devices due to their designable and controllable molecular structure， optoelectronic properties， and mechanical stretchability. The core goal of studying intrinsically stretchable organic semiconductor materials is how to improve their stretchability without sacrificing their optoelectronic properties. To this end， scholars have developed various strategies， including main chain and side chain engineering， optimizing molecular weight， as well as blending with elastomers， crosslinking agents， and adding plasticizers. Significant progress has been made in related research results. Organic semiconductors can not only achieve high stretchability， but also show good stability in repeated stretching/releasing process. However， there is still a gap in the optoelectronic performance of intrinsically stretchable organic semiconductors compared to non-stretchable materials. Therefore， more research is needed to reveal the stretching mechanism of organic semiconductor materials， strategies and methods to improve the optoelectronic performance of organic semiconductor thin films and related devices. Given the importance of intrinsically stretchable organic semiconductor research and the current challenges it faces， this article reviews the research progress in improving the tensile properties of organic semiconductor materials through molecular structure design and multi-component systems in the past decade， hoping to contribute to the further development of stretchable organic semiconductors and related optoelectronic devices.关键词：Stretchable organic semiconductors;stretchable optoelectronic devices;wearable electronic devices;molecular structure design;multi-component strategy76|117|0更新时间：2025-09-17

Broad Red Emission and Luminescence Optimization of Bi3+ Doped LaSr2SbO6 Double Perovskite 增强出版 AI导读
“最新研究发现，Bi3+离子掺杂LaSr2SbO6双钙钛矿结构可实现宽带橙红光发射，优化后发光效率达46%，为全光谱健康照明等领域提供新解决方案。”摘要：Red-emitting materials have significant applications in full-spectrum lighting， plant growth and medical health fields. Nevertheless， the development of thermally-stable broad-band red-emitting materials is still key issue. Due to the 6s2 outer electron configuration of Bi3+ ions， the energy splitting can be controllably adjusted by the surrounding crystal field environment， further achieving the luminescence tuning over the visible and near-infrared region. Herein， we successfully achieve the doping of Bi3+ ions in LaSr2SbO6 double perovskite structure with broad-band orangish red emission. LaSr2SbO6∶Bi3+ material exhibits broad excitation in the region of 300-450 nm， matching well with the commercial near-ultraviolet InGaN chip. Under 370 nm excitation， the optimal emission wavelength locates at 600 nm， with the full width at half maximum of 108 nm. The accurate structure analysis and theorical calculations confirm that Bi3+ ions preferentially occupy at La3+ site. Through adding H3BO3 as flux and designing heterovalent substitution strategy， the luminescence efficiency optimization， spectral tuning and thermal stability enhancement are further achieved. As a result， the luminescence efficiency can reach 46%， around 30 nm redshift can be adjusted. Meanwhile， LaSr2SbO6∶Bi3+ material presents superior thermal stability. Even anti-thermal-quenching performance can be obtained in the region of 77-300 K， of which the luminescence intensity at 252 K can realize 141% of that at 77 K based on the addition of H3BO3 flux. Good thermal stability can be also achieved in the region of 298-523 K， the luminescence intensity at 423 K can keep 76% than that at room temperature. The above luminescence optimization can be attributed to the following reasons. First， the addition of H3BO3 flux reduces the generation of La3SbO7 impurities and increases the crystallizes of samples. Then， heterovalent substitution strategy can induce the localized structure modulation surrounding Bi3+ ions. The proposed luminescence optimization strategy can provide reference for the development and improvement of Bi-activated red-emitting materials.关键词：Red-emitting materials;Bi3+ doped;double perovskite structure;Heterovalent substitution44|55|0更新时间：2025-09-17 - “最新研究揭示了惰性壳层介电特性对上转换纳米晶发光性能的影响，为高亮度纳米晶核壳设计提供指导。”摘要：A series of core/shell upconversion nanocrystals （UCNCs） featuring β-NaYF4∶Yb3+/A3+ （A=Er， Ho， Tm） cores and distinct inert shells （NaLuF4， NaYF4， NaGdF4） were synthesized through the co-precipitation method combined with a successive layer-by-layer strategy. The influence of shell composition on luminescent properties was investigated and the underlying mechanism was analyzed through upconversion emission spectrum and luminescent lifetime measurements. Experimental results indicate that both the upconversion luminescence intensity and the Yb3+ luminescent lifetime of core/shell UCNCs depends on the composition of inert shell， exhibiting a gradual decrease in the order of NaLuF4>NaYF4>NaGdF4. This trend suggests progressively reduced capabilities of three kinds of inert shell in suppressing surface quenching. The influences of three kinds of inert shell become more pronounced in aqueous environments with high quenching probabilities. Theoretical calculations reveal that the variation in dielectric constant among the inert shell materials may play a critical role， with NaLuF4 showing the lowest relative dielectric constant. The shell layer with low dielectric constant can mitigate the electric dipole interaction between Yb3+ ions in the core and surface-adsorbed ligands， thereby suppressing non-radiative energy losses. This study reveals the possible regulatory mechanism of the dielectric effect of inert shell on the surface quenching effect， providing valuable guidance for the compositional design of high-brightness core/shell UCNCs.关键词：Core-shell nanocrystal;upconversion luminescence;inert shell;dielectric constant88|36|0更新时间：2025-09-17

“最新研究发现，通过后处理策略制备的CsPb（Br/Cl）3纳米晶，实现了发光颜色调控和稳定性提升，为补充白光LED中所缺青光部分提供了新方案。”摘要：Inorganic perovskite CsPbX3 （X=Cl， Br， I） nanocrystals （PNCs） have the advantages of high luminous efficiency and adjustable emission wavelength， but their poor stability limits practical applications. This study employs chlorine-containing ligands for post-treatment to synthesize CsPb（Br/Cl）3 PNCs with tunable emission colors and investigates their luminescent properties and stability. The introduced Cl⁻ ions exchange with Br- in CsPbBr3 PNCs and passivate surface defects. By adjusting the concentration of the chlorine-containing ligands， the emission of CsPb（Br/Cl）3 PNCs can be tuned from green to blue light. Notably， cyan-emitting CsPb（Br/Cl）3 PNCs maintain high luminescence intensity after being immersed in water for 15 days， with stable emission peak position and full width at half maximum （FWHM）. Their photoluminescence quantum yield （PLQY） improves compared to untreated CsPbBr3 PNCs. Finally， a cyan-light-emitting diode （LED） using CsPb（Br/Cl）3 PNCs with a 370 nm chip was fabricated， achieving CIE chromaticity coordinates of （0.116， 0.264）， showing potential to supplement the cyan light in white LEDs.关键词：perovskite nanocrystals;halogenated ligand;stability;light emitting diode85|98|0更新时间：2025-09-17 - “报道了一种制备荧光颜色可调的硫量子点-硫化镉复合纳米颗粒的新方法，通过调节反应温度和溶液pH值，实现发射波长从蓝光到橙光的调控，提升了光稳定性和荧光量子产率，为荧光聚合物复合材料等领域提供新应用。”摘要：This paper presents a simple and efficient approach for preparing sulfur quantum dots-cadmium sulfide （SQDs-CdS） composite nanoparticles with tunable fluorescence colors. The successful synthesis of SQDs-CdS composite nanoparticles was verified using various characterization techniques. By adjusting the reaction temperature and solution pH， the emission wavelengths of the composite nanoparticles can be tuned across the blue-to-orange fluorescence range， effectively solving the problem of regulating SQDs’ fluorescence color. Moreover， compared to pure SQDs， the composite nanoparticles show a 25% enhancement in photostability. Meanwhile， their photoluminescence quantum yield increases by 4.54% relative to CdS quantum dots. Additionally， thanks to their excellent aqueous dispersibility， SQDs-CdS composite nanoparticles can be easily blended with polyvinyl alcohol （PVA） aqueous solution and processed into films， yielding polymer composite films that emit fluorescence in various colors.

- “最新研究突破，开发出电致变色原位可调谐近红外减光片，实现宽带均衡透过率衰减，为高性能光学元件设计提供新思路。”摘要：The tunable optical attenuator is an optical component capable of uniformly attenuating light intensity across a broad spectrum without altering the spectral distribution， demonstrating vast application potential in fields such as optical imaging， photoelectric detection， and optical communications. Unlike traditional tuning methods like mechanical rotation， the development of in situ tunable optical attenuators is key to achieving miniaturization， intelligence， and high integration of devices. Electrochromic materials， which can continuously and reversibly adjust optical transmittance under an external voltage， are ideal candidates for realizing in situ tunable optical attenuators. However， due to the limitations of their electronic structure， the spectral changes of these materials are highly uneven across different wavelengths， making it difficult to meet the requirements for broadband uniform attenuation. Additionally， commonly used transparent electrodes such as indium tin oxide （ITO） and fluorine-doped tin oxide （FTO） exhibit low near-infrared transmittance， severely restricting the development and application of near-infrared tunable optical attenuators. To address these challenges， this study deposited WO3-x films with localized coordination defects onto cerium-doped indium oxide （Ce∶In2O3， ICO） broadband transparent electrodes （covering visible to near-infrared wavelengths）， fabricating an electrochromic in situ tunable near-infrared optical attenuator. The device achieved balanced broadband transmittance attenuation （1 000-2 500 nm， with a transmittance fluctuation of only 7.2%）， a maximum optical contrast of 51.7%， coloration/bleaching response time of 6.3/4.7 s， coloration efficiency of 80.7 cm2·C-1 （at 1 000 nm）， and only a 4.7% decrease in optical contrast after 2 500 cycles. These results provide a valuable reference for the design and construction of high-performance in situ tunable near-infrared optical attenuators.关键词：in-situ tunable;near-infrared （NIR） optical attenuator;electrochromism;WO3-x;broadband transparent electrode90|154|0更新时间：2025-09-17

Electrically driven exciton light-emitting devices are crucial for exploring novel luminescent physics and advancing integrated optoelectronics applications. Currently， exciton-based light-emitting devices in 2D semiconductors primarily focus on the visible spectrum， while the fabrication of near-infrared （communication band） electroluminescent devices remains challenging. This study demonstrates electric-field-modulated excitonic near-infrared emission in bilayer and trilayer black phosphorus， and constructs injection-free exciton light-emitting devices driven by lateral electric fields. These devices operate at wavelengths around 1 150 nm and 1 500 nm， respectively. The realization of electrically driven near-infrared exciton devices using few-layer black phosphorus expands the spectral range of 2D material-based electroluminescent devices， providing new materials and pathways for near-infrared light-emitting devices.关键词：two-dimensional materials;black phosphorus;exciton;near-infrared;light-emitting diodes85|53|0更新时间：2025-09-17
- “在固态照明与显示领域，研究者构建了蓝光OLED激发荧光粉薄膜复合结构，实现了高显色指数白光器件，为新一代WOLED产业化提供技术范式。”摘要：White light organic light-emitting diodes （WOLEDs） have attracted extensive attention in the field of solid-state lighting and display due to their thinness， flexibility， and surface light source characteristics. However， WOLEDs still face challenges such as insufficient lifetime， color coordinate drift， and low power efficiency. To address these challenges， this study constructed a composite structure of blue-light OLED exciting yellow and red dual-color phosphor film. By full-spectrum matching to screen phosphors and optimizing the spectral characteristics of the phosphor film， a white light device with a high color rendering index （CRI） of 92.5 was successfully realized. By introducing SiO2 nanospheres as a dispersion medium and scattering medium， on the one hand， the aggregation of phosphors inducing Förster resonance energy transfer （FRET） effect was effectively suppressed， and on the other hand， the out-coupling efficiency of blue-light OLED was improved， increasing the device power efficiency from 47 lm/W to 58 lm/W， with a relative increase of 23%. This scheme combines the traditional advantages of OLED with the excellent stability of phosphors， simplifies the process flow， and significantly reduces production costs. Experiments show that the color coordinate shift （ΔCIE） of the device is less than 0.008 in the voltage range of 4-10 V， and it shows great application potential in high-end scenarios such as museum lighting and medical surgical lamps. This study provides a scalable technological paradigm for the industrialization of new-generation WOLEDs and has practical application value for promoting the development of healthy lighting and flexible display technologies.关键词：white light;organic light emitting diode;color coordinates;phosphor73|94|0更新时间：2025-09-17

However，by virtue of the notorious aggregation-caused quenching （ACQ） effect among traditional fluorophores， the utilizations of fluorescent functional coatings are severely limited. With the evolution of modern technology，the synthesis and development of aggregation-induced emission （AIE） materials effectively break this deadlock. Different from traditional fluorophores，AIE materials emit strong fluorescence in aggregate state while almost quenching when dissolved in soluble solvents. Owing to excellent fluorescent quantum yield，high sensitivity，photostability and outstanding resolution ratio，AIE materials are considered as pigments alternatives in coating preparation. Meanwhile，molecular structural variability induced controllable stimuli-responsive properties also provide new inspiration and feasibility for the preparation of multifunctional fluorescent films. Based on the particular emission properties of AIE materials，this article reviews the research status with regard to functional AIE fluorescent coatings in chemical detection，food and medical care，public security along with some other smart coatings. Moreover，main problems and solutions that constrain the large-scale development of functional aggregation-induced emission fluorescent coatings have been meticulously analyzed. The future research directions and application foregrounds have also been outlined.关键词：aggregation-induced emission;aggregation caused quenching;functional coatings;modifiability;stimuli-responsive75|101|0更新时间：2025-09-17
