0D perovskites have gained much attention in recent years due to their fascinating properties derived from their peculiar structure with isolated metal halide octahedra or metal halide clusters. However, the systematic discussion on the crystal and electronic structure of 0D perovskites to further understand their photophysical characteristics and the comprehensive overview of 0D perovskites for their further applications are still lacking. In this review, the unique crystal and electronic structure of 0D perovskites and their diverse properties are comprehensively analyzed, including large bandgaps, high exciton binding energy, and largely Stokes-shifted broadband emissions from self-trapped excitons. Furthermore, the photoluminescence regulation are discussed. Then, the various synthetic methods for 0D perovskite single crystals, nanocrystals, and thin films are comprehensively summarized. Finally, the emerging applications of 0D perovskites to light-emitting diodes, solar cells, detectors, and some others are illustrated, and the outlook on future research in the field is also provided.

0D 钙钛矿：独特的性质、合成及其应用

近年来，0D 钙钛矿因其具有孤立的金属卤化物八面体或金属卤化物簇的独特结构而具有令人着迷的特性，因此受到了广泛的关注。然而，仍然缺乏对0D钙钛矿的晶体和电子结构的系统讨论以进一步了解其光物理特性，以及对0D钙钛矿的进一步应用进行全面的概述。在这篇综述中，全面分析了 0D 钙钛矿独特的晶体和电子结构及其多种特性，包括大带隙、高激子结合能以及自俘获激子产生的大量斯托克斯位移宽带发射。此外，还讨论了光致发光调控。然后，全面总结了0D钙钛矿单晶、纳米晶和薄膜的各种合成方法。最后，阐述了0D钙钛矿在发光二极管、太阳能电池、探测器等方面的新兴应用，并对该领域的未来研究进行了展望。
