Broadband white-light emission with high color rendering index in a two-dimensional organic-inorganic hybrid perovskite

Abstract

Two-dimensional (2D) organic-inorganic hybrid layered perovskites have attracted increasing attention as promising candidate in optoelectronics, due to their excellent physical attributes. However, although great efforts have been made, broadband white-light emission with high color rendering index based on 2D hybrid perovskites still remain rare. Here, we report a broadband white-light emissive 2D organic-inorganic hybrid (110)-oriented perovskite, N-(3-aminopropyl)imidazole tetrachloro-lead (1), in which the 2D corrugated layered inorganic framework is formed by corner-shared highly distorted lead chloride octahedra. Remarkably, color rendering index of 1 is up to 93, which is superior to that of previously reported broadband white-light emission in 2D organic-inorganic hybrid perovskites. Such 2D hybrid layered perovskite material with high color rendering index may provide potential application in white light-emitting diodes.
