Abstract
A composition includes a plurality of lead halide perovskite nanocrystals and an ammonium halide-containing copolymer or a guanidinium halide-containing copolymer. The ammonium halide-containing copolymer and guanidinium halide-containing copolymer can include repeating units defined herein. The composition can be particularly useful for color tuning perovskite nanocrystals, and can be well-suited for light emitting applications, including light emitting diodes.
