Silica nanoparticle binder for phosphor coatings

摘要

An inorganic binder for the phosphor coatings of fluorescent lamps is described. The binder comprises silica nanoparticles which are dispersed with the phosphor in the coating. The use of lesser amounts of silica nanoparticles in place of standard aluminum oxide binders yields increased efficiency from fluorescent lamps which use vacuum ultraviolet light as a primary source of phosphor excitation. The increased efficiency is achieved without sacrificing coating adherence. <IMAGE>
