Influence of deposition temperature on ZnS thin film performance with chemical bath deposition

► ZnS films were deposited by chemical bath deposition method at different temperatures. ► The ZnS film thicknesses are about 73-200 nm. ► Annealing makes some particles grow up and the surface smooth. ► The annealed films contain Zn and S and have a microcrystalline structure. ► The ZnS films had high transmittance of about 78% in the range of 350-800 nm.
