中文摘要:
研究了Yb~(3+)掺杂铋酸盐玻璃的发光特性参数,讨论了Yb~(2+)、Bi~(3+)等缺陷淬灭中心与Yb~(3+)之间的能量转移。对于已优化的基质组成,在荧光寿命没有大幅下降的前提下,玻璃中Yb~(3+)近红外波段的发射截面明显增大,吸收截面减小,激光增益能力和饱和抽运强度均得到提高。采用有效的除羟基工艺,玻璃中不会产生比磷酸盐玻璃中更为严重的Yb~(3+)发光淬灭效应,但铋酸盐玻璃中还可能存在Yb~(2+)、Bi~(3+)等价态不稳定的缺陷淬灭中心。

英文摘要:
The luminescence property parameters of the Yb~(3+)-doped bismuthate glass are investigated,and the energy transfer from those defect quenching centers such as Yb~(2+)and Bi~(3+)to Yb~(3+)is also discussed.Based on the optimized matrix composition and without the sharp decline of the fluorescence lifetime,the near-infrared emission cross-section of Yb~(3+)in glass is obviously increased,the absorption cross-section is reduced,and the capability of laser gain and the saturation pump intensity are both enhanced.By the efficient dehydroxyl process,the luminescence quenching effect of Yb~(3+)in the bismuthate glass may not be stronger than that in the phosphate glass. However,there exist probably some defect quenching centers such as Bi~(3+)and Yb~(2+) with unstable valence states in the bismuthate glass.
