Abstract
Polarized room-temperature Raman scattering spectra measured on heat-treated GeO2-based glasses show features resembling particle peaks. They are related to the discrete particle-like structure of thermally treated samples. We have also found that our light scattering spectra have characteristic polarization properties.
