1. An optical component including an optical material comprising light-emitting quantum confined semiconductor nanoparticles having a solution quantum yield of at least 70% prior to addition to the optical material, the quantum confined semiconductor nanoparticles being distributed in a solid light transmissive host material, the optical material having been exposed to light flux for a period of time sufficient to achieve a solid state photoluminescent efficiency of the optical material greater than or equal to about 70% when excited at a wavelength of 450 nm, the solid state photoluminescent efficiency being greater than or equal to the solution quantum yield of the nanoparticles prior to addition to the optical material.
