摘要: Light-emitting devices are provided that incorporate one or more underlying LED chips or other light sources and a layer having one or more populations of nanoparticles disposed over the light source. The nanoparticles may absorb some light emitted by the underlying source, and re-emit light at a different level. By varying the type and relative concentration of nanoparticles, different emission spectra may be achieved. White light and specialty-color emission may be achieved. Devices also may include multiple LED chips, with nanoparticles disposed over one or more underlying chips in an array.

摘要: A semiconductor nanocrystal composite comprising a semiconductor nanocrystal composition dispersed in an inorganic matrix material and a method of making same are provided. The method includes providing a semiconductor nanocrystal composition having a semiconductor nanocrystal core, providing a surfactant formed on the outer surface of the composition, and replacing the surfactant with an inorganic matrix material. The semiconductor nanocrystal composite emits light having wavelengths between about 1 and about 10 microns.
