摘要

铯铅卤化物(CsPb,X,3,X,=Cl,Br,I)钙钛矿量子点以其优异的光电性能(如可调的发射光谱、高色纯度和量子效率等)引起了研究者们的广泛关注，但较差的水稳定性、热稳定性和光稳定性等缺点极大地限制了其在光电器件中的应用。目前，提高铯铅卤化物钙钛矿量子点稳定性的一种有效方法是将Cs,X,和Pb,X,2,加入惰性玻璃陶瓷基质中，只要外界提供的能量可以克服成核和晶体生长的能量障碍，玻璃中就会析出铯铅卤化物钙钛矿量子点。本文重点介绍了热处理、激光、应力和水四种铯铅卤化物钙钛矿量子点从玻璃中析出的诱导因素，并分析了每种诱导因素的优缺点，最后提出了每种诱导因素相对适合的玻璃陶瓷和一些建议。

Abstract

Cesium lead halide(CsPb,X,3,X,=Cl, Br, I) perovskite quantum dots have attracted wide attention of researchers due to their excellent photoelectric properties such as adjustable emission spectra, high color purity and high quantum efficiency. Poor water stability, thermal stability, and light stability greatly limit its application in optoelectronic devices. At present, an effective way to improve the stability of cesium lead halide perovskite quantum dots is adding Cs,X, and Pb,X,2, to the glass ceramic matrix. As long as the energy provided by the outside can overcome the energy barriers of nucleation and crystal growth, cesium lead halide perovskite quantum dots will be precipitated from glass. This paper focuses on four inducing factors for the precipitation of cesium lead halide perovskite quantum dots from glass, namely heat treatment, laser, stress and water. Finally, this paper analyzes the advantages and disadvantages of each inducing factor, and puts forward the suitable glass ceramics and some suggestions for each inducing factor.
