摘      要：yD3＋/Tm3＋ co-doped and yD3＋/Ho3＋/Tm3＋ tri-doped tellurite glasses were synthesized by fusing the mixture of TeO2, PbF2, AIF3, BaF2, Yb2O3, Tm203 and H0203 in a cortmdum crucible at 850 ℃ for 20 min. The synthesized glasses were characterized by upconversion emission spectra under the excitation of 980 nm laser, and the emission colors were investigated according to the CIE-1931 standards. The results indicated that yD3＋/Tm3＋ co-doped tellurite glass exhibited blue upconversion emission with favor- able color coordinates of （0.20, 0.07）. Yb3＋, HO3＋ and Tm3＋ tri-doped tellurite glasses presented white upconversion luminescence under a single 980 nm laser excitation. Moreover, a very wide range of emission colors could be tuned by altering Ho3＋ concentration. Combining the contribution of adjusting Ho3＋ concentration and pump power, near equal energy white light was obtained.
