| 英文摘要 | Recently, low-dimensional organic-inorganic hybrid metal halide perovskites acting as single-component white-light emitting materials have attracted extensive attention, but most studies concentrate on hybrid lead perovskites. Herein, we present two isomorphic zero-dimensional (0D) hybrid cadmium perovskites, (HMEDA)CdX4(HMEDA=hexamethylenediamine, X=Cl (1), Br (2)), which contain isolated [CdX4](2-)anions separated by [HMEDA](2+)cations. Under UV light excitation, both compounds display broadband bluish white-light emission (515 nm for1and 445 nm for2) covering the entire visible light spectrum with sufficient photophysical stabilities. Remarkably, compound2shows a high color rendering index (CRI) of 83 enabling it as a promising candidate for single-component WLED applications. Based on the temperature-dependent, powder-dependent and time-resolved PL measurements as well as other detailed studies, the broadband light emissions are attributed to self-trapped excitons stemming from the strong electron-phonon coupling. |
