Structural, optical and ammonia sensing properties of nanostructured ZnO thin films deposited by spray pyrolysis technique



In the present work, nanostructured ZnO thin films have been synthesized using spray pyrolysis technique by using the precursor solution of zinc acetate at 0.05, 0.1 and 0.15 M Concentration. X-ray diffraction patterns confirmed the polycrystalline nature of the films with hexagonal structure. The field-emission scanning electron micrograph of all the samples revealed the spherical grain value and the morphology undergoes a change according to molarity concentration. The ammonia (NH3) sensing properties of the films were performed at room temperature and the sensing responses of the samples towards NH3 concentrations were recorded.
