摘　　要：卤系钙钛矿具有吸收系数大、载流子迁移率高、荧光量子产率高、载流子寿命长、光电转化系数高、带隙可调等优异的特性,在发光二极管、太阳能电池、探测传感器、防伪等多领域,具有良好的应用前景,但其稳定性较差,易受外界环境影响(如温度、湿度),引起其发生分解、晶体结构改变、相变等,导致其光学性能减弱,局限了它的应用。目前,卤系钙钛矿稳定性仍是一个重要的研究方向。本文首先介绍了卤系钙钛矿的结构,并分析了影响卤系钙钛矿稳定性的外部因素;然后,总结了高分子配体修饰改善卤系钙钛矿稳定性的研究进展;最后,就现阶段卤系钙钛矿纳米材料研究中存在的问题及未来研究方向进行了展望。Halide perovskite exhibits exceptional optical properties,including robust light absorption,high carrier mobility,elevated fluorescence quantum yield,prolonged carrier lifetime,remarkable photoelectric conversion coefficient,and adjustable band gap.These attributes render it highly promising for diverse applications in lightemitting diodes,solar cells,detection sensors,anti-counterfeiting and other fields.However,the susceptibility of halide perovskite to external factors such as temperature,humidity,and light compromises its stability.It causes decomposition,crystal structure change,phase transition,etc.,which leads to the weakening of its optical properties and limits its application.Consequently,enhancing the stability of halide perovskite remains a crucial avenue of research.This article begins by introducing the structure of halide perovskite and analyzing the external factors that impact its stability.Then,it provides an overview of recent advancements in improving the stability of halide perovskite through polymeric ligand modification(natural polymers and synthetic polymers).Finally,it outlines existing challenges in current research on halide perovskite nanomaterials while also offering insights into future research directions.
