The gas-sensing properties of these materials against reducing and oxidizing gases were examined. The microstructure and crystal symmetry of the deposited films were studied with X-ray diffraction (XRD), Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Raman, and Photoluminescence (PL) spectroscopy. The XRD studies revealed that the ZnO films grown in an argon environment are highly textured in the c-axis with a hexagonal crystalline structure. The c-axis is perpendicular to the substrate plane orientation (002) compared to (100) plane orientation, which is developed in a vacuum environment. Usually, this orientation (100) is difficult to obtain. Raman scattering spectra for both types of ZnO films revealed the characteristic E2 (high) mode that is related to the vibration of oxygen atoms in wurtzite ZnO.
