Abstract:
White-light emissive hybrid perovskites have received continuous attention because of their potential applications in solid-state lighting and displays. However, there have been limited reports about dual-emissive white-light hybrid perovskites, although they enable a wide range of emission switching. Here, we report a one-dimensional hybrid perovskite, (N-AEP)2Pb2Cl10·H2O (NAPC, N-AEP = 1-piperazineethylammonium), which exhibits dual-emissive photoluminescence with a wide emission switch ranging from blue to orange. Significantly, tunable white-light emission from 'cold' white light (0.25, 0.29) to 'warm' white light (0.40, 0.42) can be easily observed by finely tuning the excitation wavelength. Under excitation at 335 nm, a 'cold' white light with chromaticity coordinates (0.31, 0.33) close to those of 'optimal' white light (0.33, 0.33) is achieved. Furthermore,NAPCexhibits a color rendering index reaching 93.4, which is among the highest values currently reported from white-light emissive hybrid perovskites. This work paves a way to tune the photophysical properties of hybrid perovskites, and highlights their potential for solid-state lighting applications. © The Royal Society of Chemistry 2020.
