| Abstract: | In the TeO2-WO3-GdF3 glass system, 42 different proportions of glass have been prepared, showing the ideal forming area. The influence of proportions on the density was measured and several devitrified samples were analyzed by XRD. Discussed the internal structure changes and the variation of component concentration by Raman and Fourier transform infrared spectra. The properties and structural features of glasses were analyzed in terms of molar volume. TeO2 and WO3 act as glasses former while GdF3 act as a modifier which forms mixed linkages Te–O–W, Te–F–W, etc. UV–Vis spectra were recorded to determine optical absorption/transmission and energy gap values. These results suggest that the TeO2-WO3-GdF3 glass system could be potentially used as photonic devices and basic materials. |
