Mixed-halide perovskite spectra generators

Abstract

A system may include a first emitter that includes a first mixed halide perovskite film that includes a first type mixed halide perovskite material that possesses a first usable photoemission wavelength range. The system may include a first excitation device that is positioned adjacent to the mixed halide perovskite film based on an excitation mode of the first excitation device. The first excitation device is configured to tune, based on a first instruction, the first mixed halide perovskite film to emit a first photoemission peak within the first usable photoemission wavelength range, and tune, based on a second instruction, the first mixed halide perovskite film to emit a second photoemission peak within the first usable photoemission wavelength range. The second photoemission peak has at least one of a different width or center within the first usable photoemission wavelength range than the first photoemission peak.
