Based on composition‐tunable cesium lead halide perovskite (CsPbX3, X = Cl, Br, I) microcrystal structures grown by chemical vapor deposition, broad‐band light emission devices can be achieved. Room‐temperature optically pumped red–green–blue whispering‐gallery mode lasers as well as white‐light emission are successfully realized. This work evidently suggests a feasible route to the design of red–green–blue lasers and white-light emitters for potential applications in full-color displays as well as photonic devices.
