Cesium lead halide perovskite nanocrystals (NCs) have emerged as a promising emitter for lighting and display technologies. However, the iodide-containing CsPb(Br/I)3 and CsPbI3 NCs suffer from chemical and phase degradation to nonfunctional orthorhombic (δ) phase. To address this challenge, we deve...
