Abstract

ZnO films were Prepared by ultrasonic spray Pyrolysis on MgO substrates. The surface morphology and crystallinity were observed as a function of substrate temperature by SEM and XRD, respectively. PL properties of the ZnO films were studied by using Cd-He laser. UV light around 3.37 eV was pronounced in the PL spectra. The origin of the PL peak was discussed.
