对掺Tb ~（3+）磷酸盐玻璃的热稳定性、吸收光谱、静态和瞬态发光光谱、量子效率等进行了测试和分析。当Tb ~（3+）浓度达到15mol%时，没有观察到荧光猝灭现象。掺10mol%Tb ~（3+）的磷酸盐玻璃的外量子效率为78%，是目前文献报道的最高外量子效率。玻璃的ΔT（Tx-Tg）值较大，约为340°C，保证了玻璃在拉丝过程中的热稳定性，并成功拉制出掺Tb 3+磷酸盐玻璃纤维。
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 15mol%. The external quantum efficiency of phosphate glass containing 10mol%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 ΔT (Tx–Tg) of the glasses was about 340°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.
