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)CdX (HMEDA=hexamethylenediamine, X=Cl (1), Br (2)), which contain isolated [CdX ] anions separated by [HMEDA] cations. Under UV light excitation, both compounds display broadband bluish white-light emission (515 nm for 1 and 445 nm for 2) covering the entire visible light spectrum with sufficient photophysical stabilities.

Here, by using the nontoxic silver as optically active metal center, a series of hybrid silver halides based on one-dimensional structures were constructed and realized broadband white light emission. Compounds [HDABCO][AgX(DABCO)] (X = Br (), I ()) feature one-dimensional [AgX(DABCO)] structures charged balanced by [HDABCO] cations.
