- “最新研究突破了纯ZnO半导体p型掺杂难题，成功制备了N掺杂p型透明导电MgZnOS薄膜，为全ZnO基光电子器件开发提供新思路。”摘要：In this study， to tackle the challenge of p-type doping of pure ZnO semiconductor， we proposed utilization of co-substitution strategies involving anionic （S2-） and cationic （Mg2+） ions， leveraging their synergistic effects to modify the electronic band structure of ZnO alloy to facilitate the activation of nitrogen acceptors. By applying pulsed laser deposition technique， we successfully fabricated N-doped p-type transparent conductive MgZnOS thin films. The crystal structures， optoelectronic properties， and chemical compositions of the films were systematically analyzed using X-ray diffraction， transmittance spectroscopy， Hall-effect measurements， X-ray photoelectron spectroscopy， and secondary ion mass spectrometry. The experimental results indicate that the prepared MgZnOS∶N films possess a hexagonal wurtzite structure with preferential c-axis orientation. The deposited films exhibit a transmittance exceeding 80% in the ultraviolet-visible-near-infrared spectral region， and Mg doping significantly broadens the optical bandgap of the ZnO alloy films. The Mg and S contents in the prepared p-type conductive films are 9% and 25%， respectively， and the films have a hole concentration of 2.02×1019 cm-3， a Hall mobility of 0.25 cm2/（V·s）， and a resistivity of 1.24 Ω·cm. Based on the successful fabrication of p-type MgZnOS∶N film， we designed and constructed a novel p-MgZnOS∶N/n-ZnO quasi-homogeneous p-n junction ultraviolet photodetector. The fabricated device exhibits typical diode rectification characteristics （with a turn-on voltage of approximately 1.21 V） and demonstrates stable ultraviolet photoresponse at 0 V bias， with a peak responsivity of 2.26 mA/W （at wavelength of 350 nm）. The self-driven photoresponse is attributed to the effective separation and transport of photogenerated carriers by the built-in electric field of the p-n junction. This study offers valuable insights into the p-type doping of ZnO and holds substantial significance for the advancement of high-performance all-ZnO-based optoelectronic devices.关键词：pulsed laser deposition;p-type doping;MgZnOS;p-n junction93|33|0更新时间：2025-03-24

This study introduces its research progress in optimizing diode performance by modulating oxygen vacancy concentration in InGaZnO films. Expert researchers effectively controlled the diode's electrical performance by adjusting oxygen vacancy, providing a methodology for optimizing rectifying diodes.”摘要：Rectifying circuit， as a crucial component for converting alternating current into direct current， plays a pivotal role in energy harvesting microsystems. Traditional silicon-based or germanium-based rectifier diodes hinder system integration due to their specific manufacturing processes. Conversely， metal oxide diodes， with their simple fabrication techniques， offer advantages for system integration. The oxygen vacancy defect of oxide semiconductor will greatly affect the electrical performance of the device， so the performance of the diode can be effectively controlled by adjusting the oxygen vacancy concentration. This study centers on optimizing the performance of diodes by modulating the oxygen vacancy concentration within InGaZnO films through control of oxygen flows during the sputtering process. Experimental results demonstrate that the diode exhibits a forward current density of 43.82 A·cm-²， with a rectification ratio of 6.94 × 10⁴， efficiently rectifying input sine signals with 1 kHz frequency and 5 V magnitude. These results demonstrate its potential in energy conversion and management.

- “上转换发光纳米颗粒的手性构建方法及其应用前景，为光动力学治疗等领域提供新方向。”摘要：An object （or molecule） is said to be chiral if its mirror image cannot be fully coincident by rotation or translation. Chirality is a universal basic feature in nature. Chiral materials possess unique optical properties such as circular dichroism（CD） and circularly polarized luminescence（CPL）， offering promising applications in various fields， including photocatalysis， biosensing， and optical devices. Photon upconversion（UC） refers to the process of absorbing multiple low-energy photons and emitting a single high-energy photon. Upconversion nanoparticles（UCNPs） achieve photon upconversion through energy level transitions among rare-earth ions. Chiral materials incorporating photon upconversion exhibit greater application potential in areas such as photodynamic therapy and bioimaging， owing to the advantage of low-energy near-infrared excitation. This paper introduces the chiral construction methods of upconversion nanoparticles， summarizes their chiral applications， and discusses prospects for future development.关键词：upconversion nanoparticles;chirality;circular dichroism;circularly polarized luminescence67|76|0更新时间：2025-03-24

- “最新研究发现，有机小分子钝化材料结合自组装空穴传输材料，可有效提升钙钛矿太阳电池效率和稳定性。”摘要：The buried interface defects of inverted perovskite solar cells are a significant factor that can suppress the performance and lifetime of these solar cell devices. These defects can constrain the efficiency and stability， making it crucial to solve them for improved solar cell performance. Using organic small molecules as passivation materials has been shown to be an effective strategy to mitigate these interface defects， thereby reducing the non-radiative recombination of charge carriers. In this study， we have successfully integrated a kind of passivation material with a self-assembled hole transporting layer， enabling a one-step passivation of the buried interface with a two-dimensional perovskite material. After the deposition of the perovskite film， the number of excess lead iodide particles at the buried bottom interface was significantly reduced， and the presence of two-dimensional perovskite was detected， from which it can be hypothesized that the passivation material at the bottom reacted with the lead iodide to synthesize it. This innovative approach significantly improves the efficiency of solar cells， especially the Voc and device reproducibility due to the reduction of buried interface defects. Our results demonstrate that through the passivation of the buried interface， we were able to achieve an impressive efficiency of 21.42% by using blade coating. Furthermore， to validate the scalability and practicality of our method， we fabricated perovskite solar modules with an aperture area of 21.5 cm2. These modules achieved an efficiency of 21.02% and remained stable for almost 1 000 h at 85 ℃ and 85% humidity after proper encapsulation. The simplicity and efficiency of this process confirm the potential for large-scale applications in perovskite solar cell technology.关键词：perovskite solar cell;buried interface;passivation;self-assembled monolayer;high efficiency93|64|0更新时间：2025-03-24

The Sb2O3 was successfully transferred onto an Al2O3 substrate by the chemical reaction assisted vertical micro sublimation method（CVMS）， and its properties， such as morphology and structure were characterized. The Er3+-doped passive Q-switched laser based on Sb2O3-SA was achieved by using a 978 nm pump， with the maximum single-pulse energy and the maximum peak power of 6.84 μJ and 1.12 W， respectively. With the increase of the pump power， the pulse width decreased from 19.64 μs to 6.09 μs， and the repetition frequency increased from 19.10 kHz to 62.13 kHz. The center of the output laser wavelength is located at 2 793 nm and the FWHM corresponding to the wavelength at 2 793 nm is 9.10 nm. The experimental results showed that Er3+-doped passive Q-switched lasers based on Sb2O3 saturable absorber provide a new reference to realize lower-cost， more stable ~3 μm mid-infrared lasers with simpler resonant cavity using a novel saturable absorber.关键词：Er3+;~3 μm laser;passively Q-switched;Sb2O3 saturable absorber65|13|0更新时间：2025-03-24
