Abstract
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.
