Abstract

The instability of colloidal lead halide perovskite nanocrystals (NCs) presents a significant challenge for their application in optoelectronic devices. This review examines the primary causes of instability in these NCs and the proposed mechanisms of degradation. It also introduces the recently developed synthesis and surface passivation methods to address the instability issue of colloidal perovskite NCs. Specifically, we focus on the various types of ligands and precursors introduced during NC synthesis or post-treatment and how they impact the structural and optical properties of the perovskite NCs. This review also proposes a systematic approach to evaluating stability enhancement strategies by establishing key parameters and ranking them based on working and processing conditions. Finally, we discuss the issues that need to be addressed in future research to achieve practical application of lead halide perovskite NCs in advanced optoelectronic systems.

胶体卤化铅钙钛矿纳米晶体的不稳定性：原因、改进和评价

胶体卤化铅钙钛矿纳米晶体（NCs）的不稳定性对其在光电器件中的应用提出了重大挑战。这篇综述探讨了这些NCs不稳定的主要原因和提出的降解机制。介绍了最近发展的合成方法和表面钝化方法，以解决胶体钙钛矿纳米碳的不稳定性问题。具体来说，我们关注在NC合成或后处理过程中引入的各种类型的配体和前体，以及它们如何影响钙钛矿NC的结构和光学性质。本文还提出了通过建立关键参数并根据工作和加工条件对其进行排序来评估稳定性增强策略的系统方法。最后，我们讨论了卤化铅钙钛矿NCs在先进光电系统中实现实际应用需要解决的问题。
