Abstract
A luminescent composition which is a uniform admixture of a least one phosphor having a particle size of about ten micrometers or less and at least one sol gel compound in an amount sufficient to substantially encapsulate the phosphor. Luminous devices are formed by disposing this composition on a substantially transparent substrate. The use of particulate phosphors in an encapsulating medium protects the phosphor and provides dielectric strength or conduction as required. Improved luminous devices for displays and lighting are provided such as those finding use as flat panel displays and for backlights for liquid crystal flat panel displays.
