The structural and optical properties of the as grown and thermal annealed thin films are presented. The crystalline structure was studied by X-ray diffraction (XRD) having found the presence of the CdO cubic phase pattern for low Zn concentrations and a mixing of cubic CdO and hexagonal-ZnO phases for low Cd concentrations. The crystallinity of all samples improves with the thermal annealing. The optical band-gap was also studied from the optical transmittance for the as grown and annealed samples. As expected, the band-gap changes between that for pure CdO and that for ZnO 1999 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94200979 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
