Abstract
Composite electroluminescent phosphor particles may be made by forming, on a substrate, a composite layer comprising at least one layer of a dielectric or conductive material and at least one layer of an electroluminescent phosphor, physically removing the composite layer from the substrate, and pulverizing the composite layer to obtain composite electroluminescent phosphor particles.
