SPECTRAL ANALYSIS AND APPLICATIONS OF CuNiS FILMS.

Okereke N. A., Ezenwa I. A.

Abstract

Thin films of CuNiS were grown on glass substrates by the chemical bath deposition technique. Copper (II) chloride dehydrate, nickel (II) chloride
hexahydratee and thiourea were sources of copper, nickel and sulphur ions respectively. Influence of deposition temperature on the optical and morphological properties of the films were determined. The optical characterization was done using a Shimadzu UV 1800 spectrophotometer in the wavelength range of 300-1100nm while an Olumpus microscope at X100 magnification was used to examine and produce the surface microstructure of the grown film. The optical analysis of the film revealed that the average band gap energy was 3.9 eV.

Keywords
