Abstract
Thin film of NiOx was deposited on glass slide from aqueous solutions of nickel chloride and ammonia. Ammonia was employed as complexing agent in the presence of hydroxyl solution. The film was studied using X ray diffraction, photomicrograph for the structure and absorption spectroscopy for its optical properties. The optical characterization shows that the film has band gap that ranged between 2.10eV and 3.90eV, and thickness that ranged between 0.061 and 0.346¡im. The average transmittance of films was found to be between 50% and 91% in the UV-VIS-NIR regions. The films could be effective as optical coatings for poultry houses.
Keywords: Chemical bath deposition technique; NiOx thin films; Poultry house coating.
