摘要: 有机-无机铅卤钙钛矿由于具有许多优异的光电特性而备受科研人员的关注，在先进光电子器件的多个领域中具有广阔的应用前景。但钙钛矿稳定性较差，对外界环境中的光照、湿度、极性溶剂等十分敏感，因此如何有效提高其荧光稳定性是目前研究的热点问题。本文在本科生高分子化学实验悬浮聚合的基础上，设计本科生自主高分子科学实验——“钙钛矿量子点聚苯乙烯微珠的制备及其荧光稳定性能探究”，将聚合物和钙钛矿材料相结合，通过溶胀-收缩策略将有机-无机钙钛矿材料包封在聚苯乙烯微珠中，制备杂化荧光微珠材料。此策略不仅提高了有机-无机钙钛矿材料的稳定性，又拓展了高分子科学实验产物的应用。同时，以溶胀-收缩策略作为研究领域前沿问题的切入点便于本科生理解实验原理，更能激发本科生对科学研究的兴趣。通过把前沿性研究转化为本科教学的实验教学改革模式，使学生的实验设计能力、创新能力和综合素质都得到了有效训练。

Abstract: Organic-inorganic lead halide perovskites, known for their numerous outstanding optoelectronic properties, have garnered significant interest among researchers and hold promising applications across various advanced optoelectronic devices. However, perovskites suffer from poor stability and are highly susceptible to factors such as light, humidity, and polar solvents. Consequently, enhancing their fluorescence stability remains a focal point of current research. Building on the foundation of the undergraduate suspension polymerization experiment in polymer chemistry, this study introduces an undergraduate-led polymer science experiment titled "Preparation and Fluorescence Stability of Perovskite Quantum Dots Encapsulated in Polystyrene Microbeads". This strategy combines polymer and perovskite materials, encapsulating organic-inorganic perovskites within polystyrene microbeads using a swelling-shrinkage strategy to form hybrid fluorescent microbeads. This approach not only enhances the stability of the perovskite materials but also broadens the applications of products from polymer science experiments. Additionally, employing the swelling-shrinkage strategy as a vanguard for cutting-edge research in this field not only aids undergraduates in understanding experimental principles but also greatly stimulates their interest in scientific inquiry. By translating cutting-edge research into an experimental teaching reform model for undergraduate education, students' experimental design capabilities, innovation skills, and overall quality have been effectively developed.
