Abstract

CdO/CdS/textured-ZnO/ZnO heterostructure was synthesized using a combination of electrochemical etching and chemical deposition methods. Electrochemical etching was used to form a textured ZnO layer. Chemical deposition of a solution containing CdCl₂ was performed to prepare a CdS film with CdO nanoparticles on the surface. The obtained nanocomposite was characterized using SEM, EDX and Raman methods for structural, morphological and component studies. SEM images and Raman scattering showed the existence of cubic phase of CdO nanocrystals. The SEM study revealed the dispersion of 50-200 nm agglomerated nanostructures on the surface of CdS film.
