Hybrid organic-inorganic and all-inorganic metal halide perovskites have been one of the most intensively studied materials during the last few years. In particular, research focusing on understanding how to tune the photoluminescence features and to apply perovskites to optoelectronic applications has led to a myriad of new materials featuring high photoluminescence quantum yields covering the whole visible range, as well as devices with remarkable performances. Having already established their successful incorporation in highly efficient solar cells, the next step is to tackle the challenges in solid-state lighting (SSL) devices. Here, the most prominent is the preparation of white-emitting devices. Herein, we have provided a comprehensive view of the route towards perovskite white lighting devices, including thin film light-emitting diodes (PeLEDs) and hybrid LEDs (HLEDs), using perovskite based color down-converting coatings. While synthesis and photoluminescence features are briefly discussed, we focus on highlighting the major achievements and limitations in white devices. Overall, we expect that this review will provide the reader a general overview of the current state of perovskite white SSL, paving the way towards new breakthroughs in the near future.
近年来，有机-无机杂化和全无机金属卤化物钙钛矿一直是研究最活跃的材料之一。特别是，研究重点集中在如何调整光致发光特性以及将钙钛矿应用于光电应用上，这导致了大量具有高光致发光量子产率的新材料，涵盖整个可见光谱，以及具有显著性能的器件。在已经成功将其纳入高效太阳能电池之后，下一步是解决固态照明（SSL）器件中的挑战。在这里，最突出的是制备白色发光器件。在此，我们全面介绍了使用基于钙钛矿的颜色下转换涂层制备钙钛矿白光照明器件的途径，包括薄膜发光二极管（PeLED）和混合发光二极管（HLED）。虽然简要讨论了合成和光致发光特性，但我们重点强调了白色器件中的主要成就和局限性。总的来说，我们期望本综述将为读者提供钙钛矿白色 SSL 的当前状态的概述，为不久的将来的新突破铺平道路。
