Refractive index behavior of tellurite glasses

In this paper, we investigated the experimental data of selected tellurite glasses in the form 80TeO2-5TiO2- (15x) WO3 xAnOm, and AnOm is Nb2O5, Nd2O3, Er2O3 and x = 0.1; 1; 3 and 5 mol%, by means of the refractive index obtained by the Sellmeier's coefficients and the average Polarizability determined by the Lorentz-Lorentz equation. From these results, it was possible to apply the generalized Drude-Lorentz model with the Caputo operator and thus observe that different domains of the system presented different parameters of the fractional derivative operator. These results corroborate to determine possible changes in the fractality of these vitreous systems.

Automated summary

This study investigated the physical properties of tellurite glasses using experimental data and analysis with relevant models. The results suggest that different fractional derivative operator parameters may lead to changes in the fractality of these glass systems.
