Paper Abstract

Ultrafine particle doped glass composites that show changes in optical property by gas atmosphere were developed by using the sol-gel process. The composites consist of silica glass matrix, functional ultrafine particles and micropores. Transition metal oxides or noble metals were used as the functional ultrafine particles in this study. Diameters of doped particles were confirmed to be in the order of nanometer by X-ray diffractometry and transmission electron microscopy. When the composites were exposed to NO gas flow (0.75 vol%) at 350 degree(s)C, the optical transmittance of the Au-doped composite largely decreased at 400 nm, while that of the Fe2O3- or the Co3O4-doped glass composites largely increased at 600 nm.
