摘要：

The direct current (DC) reactive magnetron sputtering of a metal copper target in oxygen-argon mixed atmospheres to produce thin films of crystalline copper oxides was described. The sputtering pressure, Sputtering power and oxygen flow rate were established in order to control ;the structures and properties of Cu2O films. The as-deposited Cu2O films with various crystal structures have high visible absorption and photo-catalytic activity under visible light irradiation. The photo-catalytic properties Of Cu2O films are affected by not only the crystal Structure but also the surface morphology.
