发明名称 NANOPARTICLE GRADIENT REFRACTIVE INDEX ENCAPSULANTS FOR SEMI-CONDUCTOR DIODES
摘要 A gradient refractive index light emitting diode is disclosed. The light emitting diode includes a die at least partially encapsulated within a polymer, and nanoparticles dispersed within the polymer along a concentration gradient related to the distance from the die. The refractive index of the nanoparticles is different from the refractive index of the polymer.

主权项 1. A gradient refractive index (GRIN) light emitting diode (LED), comprising: a die at least partially encapsulated within a polymer; and nanoparticles dispersed within the polymer, wherein the nanoparticles have a nanoparticle concentration having a continuous concentration gradient related to a distance from the die, the continuous concentration gradient extending from location at least proximate to the die towards an exterior surface of the polymer, and the nanoparticles have a nanoparticle refractive index, the polymer has a polymer refractive index, and the nanoparticle refractive index is different from the polymer refractive index.
