We prepared for Mott–Hubbard-type perovskite La0.5Sr0.5TiO3+δ thin films under an oxygen reduced environment, 5% H2/Ar. Control of the partial pressure during deposition could change the conductivity of the films, and induces a metal–insulator transition. In addition, we observed an excellent transparency at visible light with a metallic behavior, where this property could be utilized as a transparent conductor.
