Abstract

ABSTRACT

This study investigated the structural and optical properties of magnesium oxide films produced by chemical Spray Pyrolysis. They were deposited on glass substrates at 400°C and had thicknesses of 300, 400, and 570 nm. According to X-ray diffraction results, all prepared films have a polycrystalline, cubic structure. The optical characteristics (transmittance, absorption and reflectance) of films were studied for wave lengths between 300 and 900 nm and for thickness (300, 400, 570) nm at room temperature, these results showed that the absorption values increase with increasing thickness of the thin films and decreases rapidly with increasing wavelength, the reflectance values increases with increasing thickness of the thin films but increases with increasing wavelength. The results indicated that these films have an energy gap for direct transitions and that the energy gap decreases with increasing film thickness, with the forbidden direct transition energy being less than that of the allowed direct transition.
