| 摘 要： | 以正硅酸乙酯与γ-(2,3-环氧丙氧基)丙基三甲氧基硅烷为前驱体,应用溶胶-凝胶技术,合成了Tm3+离子掺杂的有机-无机复合材料。从吸收光谱特性出发,应用Judd-Ofelt理论,计算得到了Tm3+离子的J-O强度参量(Ω2,Ω4,Ω6)及Tm3+离子各激发能级的自发辐射跃迁概率、荧光分支比及辐射寿命等光谱参量。根据McCumber理论计算了Tm3+离子能级3H6←→3F4(1.8μm)跃迁的吸收截面和受激发射截面,同时,根据所获得的吸收截面、发射截面以及掺杂离子浓度等参数获得了Tm3+离子在凝胶玻璃中的增益截面函数。与其它玻璃掺杂基质比较可知,Tm3+掺杂的有机改良硅酸盐玻璃在～1.8μm和～2.0μm波段的中红外激光中有潜在的应用前景。 |

| Abstract: | Tm3+ doped organic-inorganic materials were fabricated with ethyl silicate and 3-glycidyloxypropy-trimethoxysilane as precursors by sol-gel method. According to the Judd-Ofelt theory, the Judd-Ofelt strength parameters(Ω2, Ω4, Ω6)were calculated in terms of the characteristics of the absorption spectra and the physical-chemical properties. Meanwhile, according to the McCumber theory, the absorption and stimulate emission cross-section corresponding to the 3H6←→3F4(1.8 μm) transition of Tm3+ were also calculated. The gain cross section was calculated by using the emission cross-section, absorption cross-section and Tm3+ concentration. These Tm3+-doped organic-inorganic materials would have a potential application in mid-infrared lasers at about 1.8 and 2.0 μm wavelength. |
