| 摘 要： | 根据测得的Yb^3 离子在氟铝酸盐玻璃中的吸收光谱和荧光光谱，分析了Yb^3 离子在氟铝酸盐玻璃中的吸收和发射特性，计算了Yb^3 离子的发射截面，讨论了Yb^3 离子的荧光自吸收效应和浓度猝灭效应。结果表明，自吸收效应使Yb^3 离子实测发射截面与计算所得发射截面存在较大差异并使荧光强度降低，高掺杂时Yb^3 向杂质Er^3 的能量传递是导致浓度猝灭的另一重要原因。

| Abstract: | Absorption and emission properties of Yb 3+-doped fluoroaluminate glasses were analyzed according to the measured absorption and emission spectra. The emission cross section of Yb 3+ ions was calculated. The fluorescence reabsorption effect and concentration quenching effect of Yb 3+ ions were discussed. Difference between measured emission section and calculated emission section of Yb 3+ was caused by the reabsorption effect, which also decreased the fluorescence intensity of Yb 3+ ions. The energy transfer from Yb 3+ ions to Er 3+ ions was the second key factor leading to concentration quenching in heavily Yb 3+-doped fluoroaluminate glass. |
