ABSTRACT:
A light source of coaxially stacked volumetric light cells that can be used either in a lamp or a display. Each light cell is composed of high quantum yield nanocrystals in a silica aerogel matrix that is excited by a controlled ultraviolet light source. From these stacked cell assemblies visible light is emitted of a desired color or color temperature and brightness.
