• Cu mixture led to the deposition of ZnO–CuO nanocomposite film with excess Zn onto the substrate. When this as-deposited film is annealed at 600 °C for 1 h in oxygen atmosphere, it led to the formation of Cu–Zn eutectic nanodroplets at the film surface. Since the melting point of Zn is low (419 °C

• ), during annealing at 600 °C a fraction of the excess Zn atoms evaporates by forming Zn vapor, which dissolves into the Cu–Zn eutectic nanodroplets and oxidizes forming ZnO nanoparticles. These ZnO nanoparticles formed by the catalytic action of Cu–Zn eutectic nanodroplets on the film surface combine
