| 摘 要： | 合成了Pr^3 掺杂Li2O-CdO-Al2O3-SiO2(以下简称LCAS)玻璃，对其吸收光谱和荧光光谱进行了测试和分析．在254nm UV激发下，观察到强的483nm蓝线和609nm红发射现象，对其形成机理进行了分析．根据吸收光谱和Judd-Ofelt理论，计算了该玻璃中Pr^3 离子在不同能级间的实验与理论振子强度、辐射跃迁几率、积分发射截面、荧光分支比和寿命等光谱强度参数，较大的积分发射截面显示LCAS：Pr^3 玻璃可能成为一种新的激光功能材料。

| Abstract: | Pr~(3+)-doped Li_2O-CdO-Al_2O_3-SiO_2 glass(LCAS glass) has been synthesized.The absorption spectra and fluorescence spectra of the glass were measured. Intense 483 nm blue emission and 609 nm red emission were observed under 254 nm UV excitation and their radiative transition mechanism analyzed. The experimental and theoretical strengths of oscillator in different energy levels of Pr~(3+)ion in the glass were calculated through the absorption spectra and Judd-Ofelt theory. Then the radiative transition probability, integral emission cross-sections, radiative branching ratio and lifetime spectral strength parameters of Pr~(3+)in this glass were obtained. The results show the glass is possible to be used as new laser function material. |
