Optical and thermal characteristics of glasses based on TeO.

YOUSEF, EL; AL-SALAMI, A; HOTZEL, MARIO

Glass samples have been synthesized in quaternary system based on TeO-oxide within composition, 85TeO-5NbO-5ZnO-5AgO, 68TeO-5NbO-20ZnO-7NaO and [(75− x)TeO-5NbO-20ZnO- xPbO, x = 7, 18 mol%]. Structural characterization of the glasses was studied with respect to their thermal stability, refractive indices, third order nonlinear optical susceptibility, IR spectra and Vickers hardness. For four different prepared glasses, density in the range from 5·3744 to 6·0731 g· cm, the glass transition temperature ( T) in the range from 326 to 350 °C and refractive indices, n, in the range from 2·1273 to 2·2123 at 435 nm and Vickers hardness, H in the range from 2·91 to 3·44 GPa were determined. The value of third order nonlinear optical susceptibilities ${\vert} {\chi}^{\text{(3)}}{\vert} {\approx} $ 17·9 ·10 esu of glass within composition, 68TeO-5NbO-20ZnO-7PbO, was measured by using degenerate four-wave mixing (DFWM).
