| Abstract | ||||
| The physical and optical properties of glasses having a composition [(TeO2)0.7 (B2O3)0.3]100-x (BaO) x, where (x = 50, 60, 70) have been studied. It was found that the values of density increase by increasing BaO content while as the values of molar volume and oxygen packing density decrease for all the studied samples. Also, it was found that the values of the optical energy gap decrease while as the values of the refractive index increase by increasing BaO content. The optical basicity of the glasses and the polarizability of oxide ions have been calculated. It has been found that all the studied glasses become more polarized and more basic and the entire studied samples exhibit insulating behavior by increasing BaO content. Finally, all the prepared samples have higher values of third order nonlinear susceptibility (5.361-9.635) x10-12esu; this means that all the studied samples are possibly good materials for nonlinear optical requests. | ||||
