Abstract

Brillouin and Raman measurements have been performed on silica xerogels ina wide range of densities (from 0.5 to 2.2 g cm(-3)) and temperatures (from 6 to 750 K). The experimental results show that water dynamics gives strong low-frequency Raman scattering and influences the Brillouin shift and attenuation.
