In this study, chemical bath deposition method was used to grow Zinc sulfide(ZnS) thin films from $NH_3/SC(NH_2)_2/ZnSO_4$ solutions at $90^{ circ}C$ . ZnS thin films have been prepared onto ITO glass. The concentrations of $ZnSO_4$ and $NH_3$ were varied while the concentration of Thiourea was fixed in 0.52 M. Structural, optical, electrical characteristic of ZnS thin films were measured. The physical and optical properties of different ZnS thin films were influenced severely by the concentration of the two reacting chemicals. The optimal concentration of $ZnSO_4$ and $NH_3$ was 0.085 M and 1.6 M, respectively. |
