Abstract
Light-emitting europium-doped tantalum-oxide thin films were prepared by radio-frequency magnetron sputtering. Red photoluminescence was obtained from the films after annealing by ultraviolet-laser excitation. Four peaks having wavelengths of around 600, 620, 650, and 700 nm were observed from films annealed at 600 to 900°C. The strongest intensity of the most remarkable 620-nm peak was obtained from the film annealed at 700°C for 20 min.
