Abstract
Luminescent materials include a plurality of nanocrystals. At least some of the nanocrystals may be configured to emit electromagnetic radiation upon stimulation, and the plurality of nanocrystals may exhibit a multi-modal energy level distribution. The distribution of the nanocrystals may be selectively configured to enhance the luminescence efficiency of a fraction of the plurality of nanocrystals that exhibits one energy level mode of the multi-modal energy level distribution. Light-emitting diodes and electronic devices include such luminescent materials.
