WebbCrystalline and non-crystalline nickel oxide (NiO) thin films were obtained by spray pyrolysis technique (SPT) using nickel acetate tetrahydrate solutions onto glass substrates at different temperatures from 225 to 350℃. Structure of the as-deposited NiO thin films have been examined by X-ray diffraction (XRD) and atomic force microscope (AFM). Webbto the film peak broadening is related to the size of coherently scattering domains, or the grain size, by the Scherrer equation. The grain size obtained using the 111 diffraction peaks of the NiO is tabulated in Table 1. Table .1 Structural parameters for sprayed NiO thin films by different precursor solutions.
