    Abstract

    Al2O3 nanoparticle doped SiO2-PVA nanocomposites were prepared using fumed silica, fumed alumina, and poly(vinyl alcohol) (PVA). Nanocomposites containing from 0 to 6 mol% Al2O3 were heat-treated in air at 1100 to 1300°C to obtain monolithic, transparent silica glass. The 0.6 mol% Al2O3 doped nanocomposite was sintered at 1200°C, a higher temperature than was required for the non-doped nanocomposite. The obtained Al2O3 doped silica glass exhibited characteristic blue photoluminescence (PL) on UV excitation. The effects of the Al2O3 nanoparticles on the sintering temperature and the PL characteristics of the sintered silica glass are discussed in terms of the morphology and structure of the sintered glass.
