摘要：
This work reports on an analysis of the chemical composition, structural, and optical properties of Mg-doped zinc oxide (ZMO) thin films with Mg concentration up to 54 at. % and prepared by the spray pyrolysis technique from acetate precursors. Chemical analysis show that the [Mg]/[Zn] ratio incorporated into the films is higher than that present in the starting solution. X-ray diffraction, Raman scattering, and transmission measurements show that all samples exhibit a single phase wurtzite structure with a transmittance above 70% in the visible range. Increasing Mg content leads to an increase of the band gap energy from 3.23 in pure ZnO to 3.57 eV in films with 54 at % of Mg content. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
