The color coordinates in the Commission Internationale de I'Eelairage (CIE) chromaticity diagram of Gd0.98Eu0.02-xTbxOOH, obtained under 254 nm irradiation, shifted along a straight line with the changing values ofx to include the yellow region. The CIE coordinates of Dy^3+ doped in GdOOH were located in the yellow region, while the emission intensity of Dy^3+ under 286 nm irradiation increased by more than 40 times when co-doped with Bi^3+.展开更多
