Abstract :
Thin film of zinc oxide (ZnO) was electrodeposited from an aqueous solution of Zn(NO3)2 at 70degC on indium tin oxide (ITO)-covered glass substrate. The analysis of X-ray diffraction(XRD) and scanning electron micrograph (SEM) indicated that the obtained ZnO films had a compact hexagonal wurtzite type structure with preferable (002) growth direction. A sharp near UV emission peak located at 380 nm and a strong orange emission peak located at 593 nm are observed in the photoluminescence. Meanwhile, orange red cathode-luminescence was observed and brightness of the cathode-luminescence was enhanced by annealing
