Ramírez, A. Huanosta, J. Sebastian, L. Huerta, A. Ortiz, J. Alonso] Yttria-stabilized zirconia (YSZ) films with different yttria concentrations were prepared by ultrasonic spray pyrolysis on Si substrates at 525°C, using solutions of zirconium and yttrium acetylacetonates in methanol. The chemical composition, structure and electrical properties of the films were studied by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and electrochemical impedance spectroscopy (EIS). XPS measurements show that the Y content in the films increases as the Y precursor in the solution increases. Carbon incorporation was also found in the films, although the concentration of this impurity was reduced as the incorporation of Y increased. XRD spectra show that the Zr1−x Y x O2−x/2 polycrystalline films have the cubic phase of ZrO2 and fully stabilized 8YSZ (8at.% Y2O3+92at.% ZrO2), and that their lattice constant increases slightly as the Y content increases. The conductivity of all the as-deposited films as a function of temperature, showed an Arrhenius behavior, and with the exception of the film with the maximum Y content, the activation energies were in the range of 0.98-1.11eV. The ionic conductivity of one of these films was similar to that measured for a pellet made of the 8YSZ standard powder. Springer Science+Business Media, Inc., 2006 Ramírez E.
