Outline of Final Research Achievements

Silica glass is of interest owing to its excellent properties such as low thermal expansion coefficient, high chemical durability, high mechanical strength and high transmittance from vacuum ultraviolet to near infrared. Fluorecense silica glasses with nano-fabrication are promising materials for photonics,electonics and biomaterial applications. To obtain monolithic transparent silica glass by sintering SiO2 nanoparticles, this research aims to fabricate large crack-free SiO2-PVA monoliths by investigating the preparation of SiO2-PVA suspensions; the physical properties and porous structure of the resulting SiO2-PVA nanocomposites was also examined. Fabrication of submicron patterns on silica glass by imprinting and sintering method. Monolithic silica glasses doped with rare earth ions possessed photoluminescence under UV irradiation, depending on the type of dope ions in the sintered silica glass.
