| Abstract | ||
| Two (ZnO) films were prepared by electrophoretic deposition (EPD) (ZnOEPD) and chemical spray pyrolysis (ZnOSpray) on stainless steel (St. st.) and glass substrates respectively. The sensing properties of these films to ethanol were investigated as a function to temperature. The sensitivity to ethanol increases with sample’s temperature. The method of film’s deposition is active factor on sensing properties of the films. X ray diffraction (XRD) and atomic force microscopy (AFM) techniques were utilized to study structural properties and surface topography of sensors. The results of these techniques show the differences between these films that effect on their sensing performances. | ||
