Abstract: A device including an LED light source optically coupled to a green-emitting U6+-doped phosphor having a composition selected from the group consisting of U6+-doped phosphate-vanadate phosphors, U6+-doped halide phosphors, U6+-doped oxyhalide phosphors, U6+-doped silicate-germanate phosphors, U6+-doped alkali earth oxide phosphors, and combinations thereof, is presented. The U6+-doped phosphate-vanadate phosphors are selected from the group consisting of compositions of formulas (A1)-(A12). The U6+-doped halide phosphors are selected from the group consisting of compositions for formulas (B1)-(B3). The U6+-doped oxyhalide phosphors are selected from the group consisting of compositions of formulas (C1)-(C5). The U6+-doped silicate-germanate phosphors are selected from the group consisting of compositions of formulas (D1)-(D11). The U6+-doped alkali earth oxide phosphors are selected from the group consisting of formulas (E1)-(E11).
