Abstract: Bandgap-tunable perovskite compositions are provided having the formula CsPb(A)xBy)3, wherein A and B are each a halogen. The mixed halide perovskite composition has a morphology which suppresses phase segregation to stabilize a tuned bandgap of the mixed halide perovskite composition. For example, the perovskite may be in the form of nanocrystals embedded in a non-perovskite matrix, which, for example, may have the formula Cs4Pb(A)xBy)6, wherein A and B are each a halogen. Solar cells and light-emitting diodes comprising the mixed perovskite compositions are also provided.

Abstract: Organic metal halide hybrid-based scintillation materials are provided, as well as methods of fabricating and using the same. The scintillation materials can be zero-dimensional (0D) organic metal halide hybrid-based scintillation materials, such as 4-(4-(diphenylamino) phenyl)-1-(Propyl)-pyrindin-lium zinc bromide ((TPA-P)2ZnBr4), in which at least one metal halide anion (e.g., ZnBr42−) act(s) as an X-ray sensitizer and at least one aggregate induced emission (AIE) organic cation (e.g., TPA-P+) act(s) as a light emitter.
