| 中文摘要 | 测试了不同掺杂浓度和不同厚度下Yb~(3+)磷酸盐玻璃的吸收光谱、荧光光谱和荧光寿命,计算了积分吸收截面、吸收截面、受激发射截面、自发辐射寿命以及荧光有效线宽等光谱参数,讨论了荧光俘获效应对Yb~(3+)磷酸盐玻璃光谱性质的影响.结果表明荧光俘获效应随样品厚度和掺杂浓度的增加而增大.由于荧光俘获效应的存在使得测量的Yb~(3+)磷酸盐玻璃荧光寿命明显长于计算的荧光寿命,在0.2mol%Yb_2O_3低掺杂浓度下采用不同厚度(＜4mm)的样品测量的荧光寿命之间误差为30%左右,高浓度(6mol%Yb_2O_ |
| 英文摘要 | The absorption and emission properties of the concentrations and thickness of Yb3+-doped phosphate glasses have been investigated. The integrated cross section, absorption cross section, emission cross section, the spontaneous emission probability, and the effective line width of fluorescence of Yb3+-doped phosphate glasses were determined. The effect of the radiation trapping on spectroscopic properties was discussed. It was found that the effect of radiation trapping increases remarkably with the concentration and thickness of Yb3+-doped phosphate glasses. Radiation trapping causes significant lengthening of the measured fluorescence lifetime tau(f) which is longer than the radiative lifetime tau(rad). The error in measuring the fluorescence lifetime under low Yb3+ ion concentration (0.2mol% Yb2O3) is 30% and the error is 43% under high Yb3+ ion concentration (6mol% Yb2O3) 6mol%. Radiation trapping also significantly increases the effective line width Deltalambda(eff). It will be increased by 14% and 30% larger under low and high Yb3+ ion concentration respectively. |
