中文摘要	用高温熔融法制备了Tm_2O_3掺杂浓度为0.25, 0.5, 0.75, 1, 1.25, 1.5 mol%的40 GeO_2-35TeO_2-15PbO-5Al_2O_3-2.5CaO-2.5SrO锗碲酸盐玻璃. 热学性质测试表明该玻璃的转变温度为446 ℃, 没有析晶峰. 玻璃的最大声子能量约为750 cm~(-1). 利用Judd-Ofelt 理论计算了Tm~(3+)的Judd-Ofelt 参数Omega_t(t = 2, 4, 6)、不同浓度下Tm~(3+)离子各激发态能级的自发辐射几率、荧光分支比以及辐射寿命等参数. 采用808 nm 波长抽运源测试了Tm~(3+)离子的荧光光谱. 发现掺杂浓度为1 mol% 时约1.8 mum 处的荧光强度最强. 根据McCumber 理论计算了~3F_4~3H_6的发射截面, 其峰值发射截面为6.5 * 10~(-21)cm~2. 根据速率方程计算了玻璃中OH 引起的Tm~(3+)的~3F_4能级的无辐射弛豫速率, 随着Tm~(3+)浓度增加, OH 对~3F_4能级的猝灭速率增加. 这种玻璃有望研制成一种新型的约2 mum 的激光玻璃材料.
英文摘要	Tm2O3-doped 40GeO(2)-35TeO(2)-15PbO-5Al(2)O(3)-2.5CaO-2.5SrO glasses with different Tm3+ ion concentrations are fabricated by conventional melt-quenching method. From the measurements of thermal properties it follows that the glass transition temperature is 446 degrees C and crystallization peak does not exist. The maxmium phonon energy of the host is similar to 750 cm(-1). The Judd-Ofelt strength parameter Omega(t) (t = 2, 4, 6), the radiative transition probalities, the branching ratios and the radiative lifetime are calculated according to Judd-Ofelt theory. The emission spectra of Tm3+ doped glasses with different Tm2O3 concentrations are measured under the excitation by an 808 nm diode laser. The result shows that the emission intensity at similar to 1.8 mu m reaches a maximal value when the Tm2O3-doping concentration is 1 mol% and then it decreases with the further increase of Tm2O3-doping concentration. The emission cross section of F-3(4) -> H-3(6) is calculated based on the McCumber theory. The peak emission cross-section is 6.5 x 10(-21) cm(2). The non-radiative transition rate of F-3(4) caused by OH is calculated quantitatively by rate equation. The results indicate that the germanate-tellurite glass is a new candidate for mid-infrared laser application.
