| Research Abstract |
Liquid-phase synthesis methods of silica glass, which is an important optical material because of the excellent transparency over wide spectral range, high mechanical strength, and good chemical stability, have been developed. With overcoming the fracture during drying and sintering, which has been a long-standing problem in liquid-phase synthesis of silica glasses, various opto-functionalized bulk silica glasses, such as silica glasses with low SiOH concentrations, silica glasses doped with LaF_3 nanocrystals, and silica glasses doped with rare-earth ions at high concentrations, have been developed. Furthermore, fabrication of some new silica-based materials, including polysilsesquioxane liquids and ultraviolet-transparent organic-inorganic hybrids, have been demonstrated.
