Description
Summary:Spectral characteristics of silica glasses produced from three different quartz materials by electrical fusion under vacuum, in crucible furnaces, and by flame fusion were studied by optical spectroscopy, photoluminescence and ESR spectroscopy. The effect of the annealing on the optical properties of silica glasses and quartz raw materials was investigated. Silica glass samples were annealed at 1100°C, nd samples of raw quartz were annealed at temperatures of 1600, 1650, 1700 and 1750°C. It was found that the main types of intrinsic defects in these glasses were the oxygen vacancies, and that their spectral characteristics are dependent on the local environment determined by impurities in the initial material and by the technique of glass fusion.
