Effects of nickel ion concentration on the optical and compositional studies of Cux-1 NxS thin films

I. E Ottih and A. J. Ekpunobi

Thin films of CuNiS were growm on glass substrates by solution growth deposition(SGT) technique. Copper chloride, Nickel chloride and thiourea were used as sources for Copper, Nickel and Sulphur ions respectively. The effects of nickel ion concentration on optical and compositional properties were determined. The optical and solid state properties of the deposited films were investigated by measuring the optical absorbance of the films at the normal incident of light in the range of 200 – 1000nm. This was done with the aid of a Janway 6405 UV–VIS spectrophotometer. From the absorbance values, other properties such as transmittance, reflectance, thickness and energy gap were calculated. The high transmittance and high absorbance of the film at various values of the growth parameter make the film good materials for coating in cold and temperate regions respectively. The compositional analysis was dome by Energy dispersive x-ray fluorescence (EDXRF) technique.
