IR-spectral study of the effect of WO3 on the structure of tellurite glasses
Tóm tắt
The comparison of IR-spectra of tellurite glasses and their crystal products containing from 5 up to 45 mol% WO3 indicates that the modifier does not change the coordination of tellurium. The IR-spectra of glasses containing small WO3 amounts show a band at 925 cm−1, which shifts up to 950 cm−1 with the increase in the tungsten concentration. The effect is specific of the vitreous state and may be explained by the change in the coordination of tungsten.
