Abstract: Provided herein are metal halide perovskite nanoplatelets, methods for making metal halide perovskite nanoplatelets, and devices and composite materials that include metal halide nanoperovskite nanoplatelets. The metal halide perovskite nanoplatelets may be stable at ambient temperature and pressure, thereby easing device fabrication.

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.
