A new one-dimensional face-shared hybrid lead bromide with intrinsic broadband yellow-light emission has been obtained, surpassing previously reported similar materials. The investigation of the emission mechanism in this material opens up possibilities for discovering more exceptional light-emitting materials.
A new one-dimensional (1D) face-shared hybrid lead bromide of (2cepiH)PbBr3, which exhibits intrinsic broadband yellow-light emission with a quantum yield of 16.8% outperforming all previously reported 1D face-shared hybrid metal halides, is obtained. The origin of broadband emission and the coexistence of free excitons and self-trapped excitons are deeply investigated by variable-temperature photoluminescence spectra. Our work paves the way to discovering more wonderful light-emitting materials.
