Thin films of Zinc Sulfide (ZnS) are prepared by Chemical Bath Deposition Technique using aqueous solution of Zinc acetate (Zn (CH3COO)(2)) and thiourea on glass Substrates. The Structural, Surface morphology and Optical properties of these films are investigated. The crystallinity of the thin films was characterized by means of X-ray diffraction and they all turned out to be polycrys-talline. SEM studies gives the average grain size to be small (08-130 nm) with an uneven surface feature. From FTIR analysis, films show an optical transmittance more than 70% in the visible range. Optical band gap found from the absorption study is about 3.7 eV. The physical conditions were kept identical while growing all the samples. The investigation of the effect of the synthesis method on the grain size and the effect of grain size on the properties of semiconductor is under consideration.
