Thermal annealing and density fluctuations in silica glass
Source abstract
Abstract
Abstract Silica glasses of a same composition with different annealing times above and below T g are characterized by infra-red and Raman spectroscopy in order to determine their fictive temperature. The Rayleigh scattering of these different samples is shown to decrease when the fictive temperature decreases in agreement with a decrease of density fluctuations. Some quantitative discrepancies are however shown to occur for long annealing at 950 °C.
