Abstract
ZnO/CdS bilayer films have been prepared by the chemical bath deposition (CBD) technique from a single reaction bath. The bilayer films were obtained by using solution concentrations of 1 M for ZnSO4 and 0.1 M for CdCl2. The pH was adjusted by the use of an ethanolamine-ammonia system. A solution 1 M of thiourea was used as the source of sulfur ions. The thickness of each layer in the resultant film were 2 and 0.3 μm for ZnO and CdS, respectively. We report here the optical and structural characterization of this ZnO/CdS bilayer system.
