CsGeI₃ perovskite NCs! Colloidal nanocrystals (NCs) of metal halide perovskite have recently aroused great research interest owing to their remarkable optical and electronic properties. Herein, all‐inorganic lead‐free cesium germanium iodine (CsGeI₃) perovskite NCs have been synthesized, and these CsGeI₃ colloidal NCs are confirmed to adopt a rhombohedral structure (R3m space group). Moreover, the electron beam‐induced transformations of these lead‐free perovskite NCs were investigated. The electron‐reduced Ge species revealed a distinctive transformation mechanism compared to heavier congener lead atoms in lead halide perovskite NCs. More information can be found in the Communication by Zewei Quan et al. on page 1654 in Issue 13, 2018 (DOI: 10.1002/asia.201800573).

封面功能：无铅CsGeI3钙钛矿胶体纳米晶体的合成和电子束诱导的转变（Chem.Asian J.13 / 2018）

CsGeI ₃钙钛矿NC！金属卤化物钙钛矿的胶体纳米晶体（NCs）由于其卓越的光学和电子性能，最近引起了极大的研究兴趣。在此，已经合成了全无机无铅铯锗碘（CsGeI ₃）钙钛矿型NC，并且这些CsGeI ₃胶态NC已确认采用菱形结构（R3m空间群）。此外，研究了这些无铅钙钛矿NC的电子束诱导转变。与卤化钙钛矿型NC中较重的同类铅原子相比，电子还原的Ge种类显示出独特的转变机理。有关更多信息，请参见Zewei Quan等的《通讯》。上2018年第13期第1654页（DOI：10.1002 / asia.201800573）。
