説明
Abstract We investigated relatively new techniques for densification and crystallization of sol–gel silica, titania and silica–titania coatings at relatively low temperatures. Irradiation of ultraviolet photons above the band-gap energy was found to lead shrinkage of the sol–gel films through electronic excitations. Crystallization of sol–gel titania coatings was achieved by irradiation of ultraviolet laser (4.7 eV) beam. Exposure to water vapor was shown to be effective in rearrangement of sol–gel films causing densification of silica, crystallization of titania and phase separation of silica–titania around 100°C. These techniques are useful for preparation of hard silica coatings and crystalline titania films on low-heat-resistant substrates, such as polymer plates.
