摘要

钙钛矿纳米晶体（NCs）组装成紧密排列和远程有序的超晶格，扩大了钙钛矿材料家族，并为调制其光电特性提供了平台。大量的研究致力于促进钙钛矿NC超晶格的发展。然而，由于对钙钛矿NC超晶格的合成策略、组装过程的内部相互作用以及结构的多样性缺乏全面和系统的了解，钙钛矿NC超晶格难以可控地获得和充分利用。本文综述了近年来钙钛矿NC超晶格的研究进展。本文首先讨论了钙钛矿NC超晶格的形成，涵盖了超晶格组装的各种驱动力和合成方法。然后分析了不同的超晶格结构和超晶格所表现出的迷人的光电特性。此外，还介绍了钙钛矿NC超晶格在发光器件中的应用。最后，对钙钛矿纳米超晶格目前面临的挑战和未来的发展方向进行了展望，以促进该领域的进一步发展。

Perovskite nanocrystal superlattices and their application in light-emitting devices

The assembly of perovskite nanocrystals (NCs) into close-packed and long-range-ordered superlattices has expanded the family of perovskite materials and provides a platform for modulating their optoelectronic properties. Numerous studies have been devoted to promote the development of perovskite NC superlattices. However, due to the lack of a comprehensive and systematic understanding of the synthesis strategies, internal interactions on assembly processes, and diversity of structures, perovskite NC superlattices are difficult to be controllably acquired and sufficiently utilized. In this review, recent advances in perovskite NC superlattices are summarized comprehensively and thoroughly. This review begins with the discussion on the formation of perovskite NC superlattices, covering the various driving forces and synthesis methods for superlattice assembly. The diverse superlattice structure and fascinating optoelectronic properties exhibited by superlattices are then analyzed. Furthermore, the contemporary application of perovskite NC superlattices in light-emitting devices are introduced. Finally, some perspectives on the current challenges and future directions for perovskite NC superlattices are present to promote further development in this field.
