The recent success of organometallic halide perovskites (OHPs) in photovoltaic devices has triggered lots of corresponding research and many perovskite analogues have been developed to look for devices with comparable performance but better stability. Upon the preparation of all inorganic halide perovskite nanocrystals (IHP NCs), research activities have soared due to their better stability, ultrahigh photoluminescence quantum yield (PL QY), and composition dependent luminescence covering the whole visible region with narrow line-width. They are expected to be promising materials for next generation lighting and display, and many other applications. Within two years, a lot of interesting results have been observed. Here, the synthesis of IHPs is reviewed, and their progresses in optoelectronic devices and optical applications, such as light-emitting diodes (LEDs), photodetectors (PDs), solar cells (SCs), and lasing, is presented. Information and recent understanding of their crystal structures and morphology modulations are addressed. Finally, a brief outlook is given, highlighting the presently main problems and their possible solutions and future development directions.
近年来，金属有机卤化物钙钛矿（OHPs）在光伏器件中的成功应用引发了大量相关研究，许多钙钛矿类似物被开发出来，以期寻找具有相当性能但稳定性更好的器件。在制备全无机卤化物钙钛矿纳米晶体（IHP NCs）之后，由于其更好的稳定性、超高的光致发光量子产率（PL QY）以及组成依赖性发光，其研究活动蓬勃发展，覆盖整个可见光区域且线宽较窄。它们有望成为下一代照明和显示以及许多其他应用的有前途的材料。在两年内，已经观察到了许多有趣的结果。在这里，综述了 IHPs 的合成，并介绍了它们在光电设备和光学应用方面的进展，如发光二极管（LEDs）、光电探测器（PDs）、太阳能电池（SCs）和激光等。还介绍了有关其晶体结构和形态调制的信息和最新理解。最后，给出了一个简短的展望，强调了目前存在的主要问题及其可能的解决方案和未来的发展方向。
