摘要：

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 Delta T (T-x - T-g) of the glasses was about 340 degrees C, 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.
