摘 要：Crystals of co-doped gadolinium oxyhydroxide（GdOOH）, Gd0.98Eu0.02-xTbxOOH and Gd1-y-zDyyBizOOH, were synthesized by a flux method. The color coordinates in the Commission Internationale de I’Eclairage（CIE） chromaticity diagram of Gd0.98Eu0.02-xTbxOOH, obtained under 254 nm irradiation, shifted along a straight line with the changing values of x to include the yellow region. The CIE coordinates of Dy3+ doped in Gd OOH were located in the yellow region, while the emission intensity of Dy3+under 286 nm irradiation increased by more than 40 times when co-doped with Bi3+.
