Since the initial discovery of colloidal lead halide perovskite nanocrystals, there has been significant interest placed on these semiconductors because of their remarkable optoelectronic properties, including very high photoluminescence quantum yields, narrow size- and composition-tunable emission over a wide color gamut, defect tolerance, and suppressed blinking. These material attributes have made them attractive components for next-generation solar cells, light emitting diodes, low-threshold lasers, single photon emitters, and X-ray scintillators. While a great deal of research has gone into the various applications of colloidal lead halide perovskite nanocrystals, comparatively little work has focused on the fundamental surface chemistry of these materials. While the surface chemistry of colloidal semiconductor nanocrystals is generally affected by their particle morphology, surface stoichiometry, and organic ligands that contribute to the first coordination sphere of their surface atoms, these attributes are markedly different in lead halide perovskite nanocrystals because of their ionicity.

胶态卤化钙钛矿纳米晶体的表面化学和结构

自从最初发现胶体卤化钙钛矿型纳米晶体以来，人们就对这些半导体产生了极大的兴趣，因为它们具有非凡的光电性能，包括很高的光致发光量子产率，在宽色域上的窄尺寸和可调组成的发射，缺陷耐受性，并抑制闪烁。这些材料特性使它们成为下一代太阳能电池，发光二极管，低阈值激光器，单光子发射器和X射线闪烁器的诱人组件。尽管胶态卤化铅钙钛矿纳米晶体的各种应用已得到大量研究，但相对较少的工作集中在这些材料的基本表面化学上。
