Abstract

Abstract : Blue‐Emitting Perovskite Films In article number 2103169, Zhizhen Ye, Haiping He and co‐workers report a facile vapor anion exchange method that can easily introduce Cl atoms into Br‐based films and enables preparation of blue‐emitting perovskite films with excellent surface morphology and good spectral photo‐stability. Furthermore, optically pumped blue amplified spontaneous emission is realized based on the mixed‐Br/Cl perovskite films.
