dc.description.abstractCopper Nickel Sulphide (CuNiS) thin films were deposited on glass substrate by the solution growth deposition technique (SGT). The suitability of some five complexing agents (EDTA, citric acid, tartaric acid, ammonia, and triethanolamine) were compared in the growth of the CuNiS thin film. The absorbance of the films were measured using a Cary 100 UV-Vis spectrophotometer in the wavelength range of 400 – 800 nm, from which optical properties such as transmittance, reflectance and energy band gap were further determined. The results showed the absorbance values increased in the order EDTA, citric acid, tartaric acid, ammonia, and triethanolamine, which was however in the reverse order for transmittance. Further analysis gave the band gap values of the films as 3.74, 3.34, 3.34, 3.70 and 3.45 eV’s for EDTA, citric acid, tartaric acid, ammonia, and triethanolamine, respectively. Photomicroscopic analysis of the films reveal that the smaller complexing agents presummably afforded more homogeneous films. The results obtained here indicate that CuNiS thin film may be considered as potential candidate material for the fabrication of opto-electronics devices and for use as window layer of solar cells.en_US
