摘要

卤化物过氧化物纳米晶体(HPNCs)是目前研究最深入的一组材料。在结构上与块状卤化物包晶(HPs)相关,HPNCs 是一种具有独特化学、光学和电子特性的纳米结构,具有巨大的实用潜力。在先进技术中有效利用 HPNCs 的关键之一是开发可控、可重现和可扩展的方法,以制备具有所需成分、相和形状以及低缺陷含量的材料。另一个重要条件是定量了解影响 HPNCs 化学稳定性以及光学和电子特性的因素。在此,我们将回顾这些领域的重要最新进展。在简要回顾历史之后,我们概述了制备 HPNC 的已知化学方法以及用于控制其成分、相、尺寸和形状的方法。然后,我们回顾了有关 HPNC 化学成分与光学特性之间的关系、降解机制以及电荷注入效应的研究。最后,我们进行简短总结和展望。本综述的目的不是对所有相关文献进行全面总结,而是根据作者的主观看法,选取其中最重要的最新观察结果和相关分析。

Chemical Aspects of Halide Perovskite Nanocrystals

Halide perovskite nanocrystals (HPNCs) are currently among the most intensely investigated group of materials. Structurally related to the bulk halide perovskites (HPs), HPNCs are nanostructures with distinct chemical, optical, and electronic properties and significant practical potential. One of the keys to the effective exploitation of the HPNCs in advanced technologies is the development of controllable, reproducible, and scalable methods for preparation of materials with desired compositions, phases, and shapes and low defect content. Another important condition is a quantitative understanding of factors affecting the chemical stability and the optical and electronic properties of HPNCs. Here we review important recent developments in these areas. Following a brief historical prospective, we provide an overview of known chemical methods for preparation of HPNCs and approaches used to control their composition, phase, size, and shape. We then review studies of the relationship between the chemical composition and optical properties of HPNCs, degradation mechanisms, and effects of charge injection. Finally, we provide a short summary and an outlook. The aim of this review is not to provide a comprehensive summary of all relevant literature but rather a selection of highlights, which, in the subjective view of the authors, provide the most significant recent observations and relevant analyses.
