Lead halide perovskites (LHPs) in the form of nanometre-sized colloidal crystals, or nanocrystals (NCs), have attracted the attention of diverse materials scientists due to their unique optical versatility, high photoluminescence quantum yields and facile synthesis. LHP NCs have a ‘soft’ and predominantly ionic lattice, and their optical and electronic properties are highly tolerant to structural defects and surface states. Therefore, they cannot be approached with the same experimental mindset and theoretical framework as conventional semiconductor NCs. In this Review, we discuss LHP NCs historical and current research pursuits, challenges in applications, and the related present and future mitigation strategies explored.

胶态卤化钙钛矿纳米晶体的成因,挑战和机遇

纳米级胶体晶体或纳米晶体(NCs)形式的卤化钙钛矿(LHP),由于其独特的光学多功能性,高的光致发光量子产率和易于合成的特性而吸引了众多材料科学家的关注。LHP NCs具有“软”且主要为离子晶格,其光学和电子特性对结构缺陷和表面状态具有高度的耐受性。因此,不能用与常规半导体NC相同的实验思维和理论框架来接近它们。在这篇评论中,我们讨论了LHP NCs的历史和当前的研究追求,应用中的挑战以及相关的当前和未来的缓解策略。
