ABSTRACT:
An optical material is provided. The optical material includes a nanoparticle-resin composite material in which metal oxide nanoparticles are dispersed in a polymer, wherein the metal oxide nanoparticles are crystalline and have a particle diameter of 1×10−8 m or less, wherein surfaces of the metal oxide nanoparticles are coated with a surfactant, and wherein the metal oxide nanoparticles are crystallized at a temperature greater than or equal to 200° C. and less than or equal to 400° C. A light assembly including the nanoparticle-resin composite material is also provided.
