Zero‐Dimensional Perovskites In article number 201900127 , Xiaosheng Tang, Juan Du, Yuxin Leng, and co‐workers study the photophysical properties of zero‐dimensional Cs 4 PbBr 6 by using femtosecond transient absorption measurements; the existence of polarons provides evidence of the inherent green emission from Cs 4 PbBr 6 . Furthermore, the excellent stable lasing performance at room temperature from Cs 4 PbBr 6 perovskite microdisks is successfully achieved.
