The cover feature shows a white‐light‐emitting electrochemical cell (WLEC) composed of the non‐doped blue‐green LEC and the single composition perovskite nanocrystals, which serves as a color conversion layer. A laser scanning technique widely tunes the color temperature of the WLEC by modifying the perovskite nanocrystals. This approach has potential to simplify fabrication of the light sources for bedrooms, living room and working place. Details are given in the Full Paper by H. C. Su, Z. P. Yang and co‐workers on page 239 in Issue 4, 2018 (DOI: 10.1002/cplu.201700422).

封面功能：通过激光扫描钙钛矿-纳米晶体颜色转换层来调整发白光电化学电池的色温（ChemPlusChem 4/2018）

封面特征显示了白色发光电化学电池（WLEC），该电池由未掺杂的蓝绿色LEC和单一成分的钙钛矿纳米晶体组成，用作颜色转换层。激光扫描技术通过修饰钙钛矿纳米晶体来广泛地调节WLEC的色温。这种方法具有简化卧室，客厅和工作场所的光源制造的潜力。有关详细信息，请参见H.C. Su，Z.P.Yang及其同事在2018年第4期第239页上的内容（DOI：10.1002 / cplu.201700422）。
