Abstract
In this study, (NiO) thin film which prepared by chemical method and deposited by drop casting technique on glass. The structural, optical and chemical analyses have been investigated. X-ray diffraction (XRD) measurements relieve that the (NiO) thin film was polycrystalline, cubic structure and there is no trace of the other material. UV-Vis measurements reveal that the energy gap of (NiO) thin film was found 1.8 eV. The Fourier Transform Infrared Spectroscopy (FTIR) spectrum of (NiO) thin film shows NiO nanoparticles had its IR peak of Ni–O stretching vibration and shifted to blue direction. Due to their quantum size effect and spherical nanostructures, the FTIR absorption of NiO nanoparticles is blue-shifted compared to that of the bulk form.
