| 摘 要： | 研究了Na2O含量对Na2O-Al2O3-SiO2(NAS)玻璃的光谱性质的影响。利用Judd-Ofelt(J-O)理论和吸收光谱计算了Er^3 掺杂的铝硅酸盐玻璃的Ωt参数、自发辐射几率和自发辐射寿命，分析了Ωt参数与Na2O含量的关系以及与吸收截面，Er^3 离子^4I13 2能级的自发辐射几率和荧光半峰全宽(FWHM)等性质的关系。随Na2O含量的增加．J-O参数Ωt(t=2，4，6)减小，Er^3 离子1533nm的吸收截面和荧光半峰全宽．Er^3 离子^4I13 2能级的自发辐射几率也减小，而Er^3 离子的荧光寿命增大。

| Abstract: | The effects of Na2O contents on spectroscopic properties of Er3+-doped Na2O-Al2O3-SiO2 glasses were studied in this paper. The Ωt parameters, radiative transition probability, and radiative lifetime of the Er3+-doped sodium aluminosilicate glasses were calculated by the Judd-Ofelt (J-O) theory and absorption spectra. Then the relationship between Ωt parameters and Na2O contents, and the effect of Na2O contents on absorrption cross section, and the spontaneous emission probability of the 4I13/2 level of Er3+, and the full width at half maximum(FWHM) of 1.53 μm were analysed. |
