【 摘 要 】

Glass samples have been synthesized in quaternary system based on TeO₂â€�?�oxide within composition, 85TeO₂â€�??5Nb₂O₅â€�??5ZnOâ€�??5Ag₂O, 68TeO₂â€�??5Nb₂O₅â€�??20ZnOâ€�??7Na₂O and [(75−ð�?��?)TeO₂â€�??5Nb₂O₅â€�??20ZnOâ€�?�ð�?�¥PbO, ð‘�? = 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^-1, the glass transition temperature (ð‘�??_g) in the range from 326 to 350 °C and refractive indices, ð‘�??, in the range from 2.1273 to 2.2123 at 435 nm and Vickers hardness, 𝐻_v, in the range from 2.91 to 3.44 GPa were determined. The value of third order nonlinear optical susceptibilities |ðœ�?⁽³⁾| â‰�? 17.9 .10^-13 esu of glass within composition, 68TeO₂â€�??5Nb₂O₅â€�??20ZnOâ€�??7PbO, was measured by using degenerate four-wave mixing (DFWM).
