Abstract
The Mg x Zn1−x O alloy thin films were synthesized on Si and quartz substrates by the sol-gel deposition method. The transmittance and cathodoluminescence spectra of the Mg0.05Zn0.95O and Mg0.15Zn0.85O nanoparticle films were obtained at room temperature. It was found that the bandgap of Mg0.05Zn0.95O and Mg0.15Zn0.85O films is as large as 3.72 eV and 3.79 eV, respectively. The ultraviolet emission peaks are located at 376 nm and 370 nm, respectively, for the samples annealed at 600°C. When the annealing temperature is elevated to 1000°C, the band-gap decreases to 3.42 eV and an emission line related to the deep-level defect appears at 500 nm. The mechanism behind these phenomena is discussed.
