  ABSTRACT: We prepared CuO-Ta2O5 composite films by our simple co-sputtering method using three CuO pellets and a Ta2O5 disc as a co-sputtering target, and subsequently annealed the films in ambient air at 900℃, 1000℃, and 1100℃ for 20 min. We evaluated photoluminescence (PL) and X-ray diffraction properties of the annealed films, and discussed the relationship between sharp PL peaks (λ ~ 450 nm) observed from all the films and their crystallizabilities. We considered that the 450-nm peaks originated from Cu2.1(Ta4O12) crystal phases in the films.
