Thermal stabilities, absorption spectra, static and transient luminescence spectra, quantum efficiencies were measured and analyzed for the phosphate glasses doped with Tb³⁺. No fluorescence quenching was observed even when Tb³⁺ concentration reached 15 mol % . The external quantum efficiency of phosphate glass containing 10 mol %  Tb³⁺ was measured to be 78 % , which is the highest up to date compared with other Tb³⁺-doped materials reported in previous literatures. The large value of ¦¤T (T_x - T_g) of the glasses was about 340 ¡ãC, which guarantees the thermal stability of the glasses against crystallization during the fiber drawing process, and Tb³⁺-doped phosphate glass fibers have been successfully drawn.
