Abstract
Effects of substrate and wavelength on the crystallinity and surface morphology of UV irradiated zirconia thin films were investigated. The surface morphology of alkoxy-derived zirconia thin films changed in case of UV irradiation using an ultra-high pressure mercury lamp at room temperature. On the other hand, the crystallinity of zirconia thin films increased in case of UV irradiation using a low pressure mercury lamp at room temperature. The substrate and wavelength were considered to play important roles in the reaction.
