Abstract

This study reports the fabrication of a bi-structured zinc oxide (ZnO) film via electrodeposition onto conductive coated glass. The produced ZnO film exhibits a polycrystalline nature with preferential orientation toward the c-axis. Scanning electron microscopy (SEM) images of the film show the presence of two structures: the bottom layer consisted of sub-micron particles with a hexagonal structure, and plate-like structures of ZnO grew on the top of the hexagonal particles. The ZnO exhibited a weak emission in the UV band and no visible emissions were observed. Blue and red emissions appeared at 2.83 eV and 1.63 eV, respectively, and were attributed to the defect concentrations of oxygen interstitials and zinc vacancies.
