SEMICONDUCTOR NANOPARTICLE-BASED LIGHT EMITTING DEVICES AND ASSOCIATED MATERIALS AND METHODS

摘要

The present invention relates to a formulation for use in the fabrication of a light emitting device said formulation comprising a population of semiconductor nanoparticles incorporated into a plurality of discrete microbeads (4, 5) comprised of an optically transparent medium, said nanoparticle-containing medium being embedded in a host light emitting diode (1) encapsulation medium (3). A method of preparing such a formulation is described. There is further provided a light emitting device including a primary light source in optical communication with such a formulation and a method of fabricating the same.
