| Özet |
| We have investigated the mechanisms which are contribute to the linear and nonlinear optical behaviors of the heavy metal containing tellurite glasses by using UV-Vis spectrophotometer and open aperture Z-scan experiments. The bandgap values of the studied tellurite glasses with WO 3 , Nb 2 O 5 , and ZnO modifiers were found among 2.58 eV and 3.01 eV. The results of the open aperture Z-scan experiments indicated that the studied tellurite glasses modified with different amounts of WO 3 , Nb 2 O 5 , and ZnO possessed larger nonlinear absorption coefficients (among 2.62x10 -7 cm/W and 6.38x10 -7 cm/W) than the nonlinear absorption coefficients of previously investigated tellurite glasses. When the linear and nonlinear absorption results of the studied modified tellurite glasses considered together, it can be reported that the mechanisms which are contributed to the nonlinear absorption coefficients caused mainly from two photon absorption and two photon assisted free carrier absorption. |
