Tunable broad-band white-light emission in two-dimensional (110)-oriented lead bromide perovskite (C₃H₈N₆)[PbBr₄]: optical, electronic and luminescence properties

The 2D-perovskite (C 3 H 8 N 6 )[PbBr 4 ] shows white-light emission with room-temperature phosphorescence based on the strategy of heavy-atom-participated anion–π + interactions.
