OSTI ID:644430
A method for generating well-crystallized photo- and cathodoluminescent oxide phosphor powders is disclosed. The method of this invention uses hydrothermal synthesis and annealing to produce nearly monosized (RE{sub 1{minus}x}Ln{sub x})(P{sub 1{minus}y}V{sub y}O{sub 4}) (Ln{double_bond}Ce{yields}Lu) phosphor grains with crystallite sizes from 0.04 to 5 {micro}m. Such phosphors find application in cathode-ray tube, flat-panel, and projection displays. 4 figs.
