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.

热水处理(HWT)是一种有效的低温结晶技术，用于溶胶-凝胶法制备TiO_2、ZnO、SnO_2和WO_3等氧化物。还发现碱-HWT允许化学稳定的ZrO_2和BaZrO_3结晶。通过HWT获得的锐钛矿纳米晶分散薄膜成功应用于染料敏化太阳能电池的光电极。此外，Pd光沉积锐钛矿纳米晶体分散薄膜可作为光学氢传感器用于实际应用。对无机-有机杂化物进行了纳米压痕测试。含有苯基的薄膜表现出显着的可塑性，有望用于室温纳米压印。乙烯基和二氧化钛组分的添加诱导了所得薄膜的紫外硬化性能。光敏杂化薄膜中，Ag/AgCl-RSiO_<3/2>-TiO_2和偶氮苯掺杂的RSiO_<3/2>薄膜表现出可逆的光学变化，可应用于全息记录。
