Effect of deposition variables on properties of CBD ZnS thin films prepared in chemical bath of ZnSO4/SC(NH2)2/Na3C3H5O7/NH4OH

► The CBD ZnS thin films were prepared on soda lime glass in a bath of ZnSO4/SC(NH2)2/Na3C3H5O7/NH4OH. ► The transmittance for ultraviolet-visible rays (300-800 nm) through those films is in a range of 70.8-87.8%. ► The ZnS thin films have an energy gap from 3.885 to 3.980 eV which increases with the decrease of ZnSO4 concentration. ► The CBD ZnS thin film with a Zn/S of 1:1 could be prepared at 80 °C in chemical bath.
