Progress in the research of perovskite quantum dots with total inorganic cesium lead halogen

摘要:

全无机铯铅卤钙钛矿（CsPbX3（X=Cl、Br、I））量子点稳定性高、色纯度好、量子产率高，受到人们广泛的关注。然而，CsPbX3量子点中组分铅的毒性限制了CsPbX3量子点的进一步应用，同时，如何进一步提升其性能和稳定性也备受关注。文章首先对CsPbX3量子点进行了简介，进而综述了选择合适的方法包括掺杂控制其晶粒尺寸、包覆钝化提高稳定性等（包覆剂、钝化剂、技术方法等）的研究进展。最后，笔者对CsPbX3量子点未来的发展方向进行了展望。

Abstract:

Total inorganic cesium lead halide perovskite (CsPbX3 (X=Cl、Br、I)) quantum dots have high stability, high color purity and high quantum yield, which has attracted wide attention. However, the toxicity of component lead in CsPbX3 quantum dots limits the further application of CsPbX3 quantum dots. Meanwhile, how to further improve its performance and stability also attract much attention. In this paper, a brief introduction of CsPbX3 quantum dots is presented. Furthermore, the research progress of selecting appropriate methods, including doping to control grain size and coating passivation to improve stability (coating agent, passivating agent, technical methods, etc.), is reviewed. Finally, the development direction of CsPbX3 quantum dots in the future is prospected.
