| Abstract: | The structure of 65SnF2-35GaF3, 75SnF2-25GaF3, and 85SnF2-15GaF3 glasses is studied using Raman and IR spectroscopy. The glass structure in the SnF2-GaF3 system is formed by a mixed network of fluorogallate and fluorostannate groups. A boson peak is observed in the low-frequency region (～29 cm?1) of the Raman spectra of the glasses. The shape of the boson peak signifies that the glass does not separate into components on the nanometer scale. |
