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.

基于白色钙钛矿的照明设备

在过去的几年中，杂化有机-无机和全无机金属卤化物钙钛矿已成为研究最深入的材料之一。尤其是，专注于理解如何调整光致发光特征以及如何将钙钛矿应用于光电应用的研究已经导致了无数新材料的出现，这些材料具有覆盖整个可见光范围的高光致发光量子产率以及具有出色性能的器件。已经成功地将其纳入高效太阳能电池中，下一步就是应对固态照明（SSL）器件中的挑战。在这里，最突出的是制备白色发射器件。在此，我们全面介绍了钙钛矿白色照明设备的发展路线，包括使用基于钙钛矿的彩色降频转换涂层的薄膜发光二极管（PeLED）和混合型LED（HLED）。在简要讨论合成和光致发光功能时，我们重点介绍了白色器件的主要成就和局限性。总体而言，我们希望这篇评论能够为读者提供钙钛矿白色SSL当前状态的概述，为在不久的将来取得新的突破铺平道路。
