Abstract
Titanium dioxide (TiO2) has a variety of functions, but cannot be activated by visible-light illumination. It is importance to extend the activity of TiO2 into the visible-light, which comprises the larger portion of the room light. Therefore, the visible-light activated TiO 2 is required. We developed it with the femtosecond laser irradiation. The TiO2 films irradiated with femtosecond laser were darkened without changing topography of the TiO2 film surface. In the visible-light photocataltic function measurements, the TiO2 films were evaluated with the acetaldehyde decomposition test. The concentration of acetaldehyde was decreased to over time. This result indicated that visible-light activated photocatalyst function of TiO2 films were generated by femtosecond laser irradiation.
