Abstract

A device including an LED light source optically coupled to a green-emitting U-doped phosphor having a composition selected from the group consisting of U-doped phosphate-vanadate phosphors, U-doped halide phosphors, U-doped oxyhalide phosphors, U-doped silicate-germanate phosphors, U-doped alkali earth oxide phosphors, and combinations thereof, is presented. The U-doped phosphate-vanadate phosphors are selected from the group consisting of compositions of formulas (A1)-(A12). The U-doped halide phosphors are selected from the group consisting of compositions for formulas (B1)-(B3). The U-doped oxyhalide phosphors are selected from the group consisting of compositions of formulas (C1)-(C5). The U-doped silicate-germanate phosphors are selected from the group consisting of compositions of formulas (D1)-(D11). The U-doped alkali earth oxide phosphors are selected from the group consisting of formulas (E1)-(E11).
