| Research Abstract |
Hot-water treatment (HWT) was an effective technique of low temperature crystallization for the sol-gel-derived oxides such as TiO_2, ZnO, SnO_2 and WO_3. It was also found that the base-HWT allowed crystallization of chemically stable ZrO_2 and BaZrO_3. Anatase nanocrystal-dispersed films obtained by HWT were successfully applied as photo-electrodes for dye sensitized solar cells. In addition, Pd-photodeposited anatase nanocrystal-dispersed films were useful as an optical hydrogen sensor for the practical application.
Nano-indentation tests were performed for the inorganic-organic hybrids. The films containing phenyl group showed significant plasticity and were promising for the nano-imprinting at room temperature. The addition of vinyl group and titania component induced the UV hardening property of the resultant films. Concerning the photo-sensitive hybrid films, Ag/AgCl-RSiO_<3/2>-TiO_2 and azobenzene-doped RSiO_<3/2> films showed reversible optical changes and can be applied to holographic recording.
