The lack of highly efficient blue‐emitting perovskite nanocrystals limits their development for optoelectronic applications. In article number 2001698, Bartomeu Monserrat, Shuyu Zhang, and co‐workers develop blue‐emitting neodymium‐doped CsPbBr3 nanocrystals with high photoluminescence quantum yield (PLQY) and narrow spectral width. First principles calculations reveal the microscopic mechanisms for the blueshift of photoluminescence and the enhancement of PLQY upon doping.

钙钛矿纳米晶体：通过钕掺杂实现高效发蓝光的CsPbBr3钙钛矿纳米晶体（Adv。Sci。20/2020）

缺乏高效发蓝光的钙钛矿纳米晶体限制了其在光电应用中的发展。在第2001698号文章中，Bartomeu Monserrat，Zhangyu Zhang和他的同事开发了发射蓝光的掺钕CsPbBr3纳米晶体，具有高光致发光量子产率（PLQY）和窄光谱宽度。第一性原理计算揭示了掺杂后光致发光蓝移和PLQY增强的微观机制。
