%X We prepared CuO-Ta<sub>2</sub>O<sub>5</sub> composite films by our simple
co-sputtering method using three CuO pellets and a Ta<sub>2</sub>O<sub>5</sub> disc as a co-sputtering target, and subsequently annealed the films in ambient
air at 900¡æ, 1000¡æ, and 1100¡æ for 20 min. We evaluated photoluminescence (PL) and X-ray diffraction
properties of the annealed films, and discussed the relationship between sharp
PL peaks (<i>¦Ë</i> ~ 450 nm) observed from all the films and their crystallizabilities. We
considered that the 450-nm peaks originated from Cu<sub>2.1</sub>(Ta<sub>4</sub>O<sub>12</sub>)
crystal phases in the films.
