Abstract

Component doping is the fundamental topic for modulating the properties of semiconductor materials. The introduction of doping ions into lead halide perovskites (LHPs) can not only maintain the excellent photoelectric properties but also enhance the stability of LHPs in open air and thermal environments. However, due to the “self-purification” effect in crystallography, there is an inherent trend to pop doping ions out of LHPs lattice. In this work, it is confirmed that in Mn2+ doped LHPs nanocrystals (NCs) the discharge of Mn2+ will be accelerated at higher temperatures. It is also proved that even at room temperature, the dopants in LHPs NCs will also actively “migrate”, resulting in declined optical performance. Therefore, for cation alloying/doping LHPs NCs, the migration of doping ions in the material should be considered in addition to the intrinsic halide migration characteristics. This work will provide a benign reference for application of doped LHPs NCs.

影响掺锰卤化物包晶石纳米晶体光学性能的自净化技术
成分掺杂是调节半导体材料性能的基本课题。在卤化铅包晶石(LHPs)中引入掺杂离子,不仅能保持其优异的光电特性,还能增强其在露天和热环境中的稳定性。然而,由于晶体学中的 "自净化 "效应,掺杂离子有从 LHPs 晶格中析出的固有趋势。这项研究证实,在掺杂了 Mn2+ 的 LHPs 纳米晶体(NCs)中,Mn2+ 在较高温度下会加速放电。同时还证明,即使在室温下,LHPs NCs 中的掺杂剂也会主动 "迁移",从而导致光学性能下降。因此,在进行阳离子合金化/掺杂 LHPs NCs 时,除了考虑固有的卤化物迁移特性外,还应考虑材料中掺杂离子的迁移。这项工作将为掺杂 LHPs NCs 的应用提供良性参考。
