用传统熔融法制备了一种新型的氧氯碲酸盐玻璃: (90-x)TeO2-10Nb2O5-xBaCl2 (x=10, 20, 30),用密度比重天平、显微拉曼光谱仪、红外-可见-紫外分光光度计和棱镜耦合仪研究了组分变化对玻璃密度、结构、光学性质、折射率和色散的影响. 研究结果表明:随玻璃中BaCl2含量增加, 玻璃密度出现了先增大后减小的现象; 玻璃结构中双三角锥体[TeO4]量减少, 三角棱锥体[TeO3]量增加; 玻璃的折射率逐渐减小. 新型的氧氯碲酸盐玻璃具有较高的线性折射率nmax=2.02259, 非线性折射率N2=6.8× 10-12 esu与三阶非线性极化率χ(3)=3.7× 10-13 esu. 制备的新型碲酸盐玻璃在可见和中红外光谱区具有高透过, 在近紫外光谱区具有明显的吸收截止波长,且随BaCl2含量增加吸收截止波长发生了明显的蓝移现象.利用经典的Tauc方程计算了玻璃样品的直接跃迁光学帯隙和间接跃迁光学帯隙,玻璃的光学帯隙随BaCl2含量增加而增大.Oxygen-chlorine tellurite glasses: (90-x)TeO2-10Nb2O5-xBaCl2 (x=10, 20, 30) are prepared using the conventional melting method. The influences of component on the density, structure, optical properties, refractive index and dispersion of the glasses are studied using density specific gravity balance, Raman spectroscopy, infrared-visible-UV spectrophotometer and Prism Coupler. The results show that the glass density first increases and then decreases with the increase of content of BaCl2. Furthermore, the structural units are converted from [TeO4] trigonal bipyramid into [TeO3] trigonal pyramid. Moreover, glass refractive index gradually decreases. In addition, new tellurite glass has high linear refractive index n (2.02259), nonlinear refractive index N2 (6.8× 10-12 esu) and third-order nonlinearpolarizability χ(3)(3.7× 10-13 esu). The new tellurite glass exhibits a high transmittance in the visible and infrared spectral region and possesses an cut-off edge in the near UV spectral region, and they each undergo an obvious blue shift with the increase of content of BaCl2. The direct and indirect transition optical band gaps of the samples are calculated according to the Tauc equation, and they increase with the content of BaCl2 increasing.
