Light scattering from glass-forming molten salts

Abstract

Raman scattering has been employed to study the temperature and polarization dependence of the vibrational modes for the glass-forming halide salt mixtures xZnCl2-(1 - x)AlCl3, with x = 0.8 and 0.6. The analysis has shown that the vibrational modes of the mixtures arise from a contribution of the vibrational modes of the pure components Salts. Emphasis has also been given to the low-frequency modes (3 - 80 cm-1), and particular points related to the glass transition phenomenology are discussed in view of the experimental findings.
