Abstract

The effect of Zn concentration was investigated on optical and morphological properties of synthesized Zinc Sulphide thin film (ZnS). . ZnS thin films were prepared at different concentrationsof ZnSO 4( zincsulphate) onto the glass substrates by chemical bath deposition technique at a constant deposition temperature and time of 500C and 1 hour respectively. .The precursor was prepared using mixed aqueous solution of zinc sulphate as a source of zinc and thiourea as a source of sulphur while ammonia serves as a complexing agent. After the deposition, thickness of the samples were determined using double weighing method. Morphological and optical properties of the films were determined using scanning electron microscope (SEM PHENON WORD) andUV-visible double beam spectrophotometer (ATICO) respectively. The result shows that transmittance spectral increases in the visible region of wavelength 400nm to 800nm and decreases in the infrared region at above 800nm wavelength.. The extrapolated optical band gap energy for the film deposited is between 3.6 -3.8 eV. The microstructural images of all the samples were rough and the grains were dense.
