Organometal Halide Perovskite Nanoplatelets, Devices, and Methods

摘要

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.
