A novel spontaneous radiation amplification strategy for trihalide perovskite films is demonstrated by Yinzhou Yan and co‐workers in article number 2001932. A patterned microsphere monolayer is capped on the perovskite microcrystal film achieving selective luminescence enhancement with highly‐directional emission. Such a vertical structure will have great application prospects in future light‐emitting and optoelectronic devices. Impact by chinese dragon and phoenix on the cover points to promising prospects of the research on microsphere‐enhanced luminescence for novel perovskite materials.
