Abstract
The deformation potential in x Nb2O5 - (1-x) TeO2, 0.1 PbO - x Nb2O5 - (0.9-x) TeO2 and 0.2 PbO - x Nb2O5 - (0.8-x) TeO2 tellurite glass systems, was calculated using the Central Force Theory (CFT). Analysis of the compositional dependence of the experimental deformation potential in the three glass systems has been achieved. The quantitative analysis was based on the number of oxygen atoms that vibrate in the double well potential, the deformation potential and the mutual potential energy according to (CFT) with longitudinal elongation. Comparisons between the previous measured values and the predicted values using the Artificial Neural Network (ANN) model for 11 different tellurite glass compositions have been implemented which showed good agreement between them.
