Abstract

Silver-doped (Ag) and magnesium-doped (Mg) zinc oxide (ZnO) thin films were fabricated on silicon using intermittent spray pyrolysis. Undoped ZnO thin film was also fabricated as a reference. The scanning electron microscope (SEM) images of the ZnO thin films revealed a very rough surface morphology. The x-ray diffraction (XRD) profile showed that the thin films have a hexagonal wurtzite crystal structure. The UV-VIS spectra showed that the ZnO thin films have high transparency in the visible region. Wide-scan photoluminescence (PL) spectra of all the ZnO thin films indicate UV and visible emissions at around 380-400 nm and 510-530 nm, respectively. An increase in green emission and decrease in bandgap for Ag-doped ZnO thin film were observed, making Ag a viable dopant to extend the operation of future ZnO-based optoelectronic devices to the visible region.
