Languages of publication
This research deals with the study of the structural and optical properties of CuO and Cd doped CuO nano films in thickness 100nm were deposited on a glass substrate using sol-gel spin coating technique. XRD results indicated that the films are polycrystalline and have monoclinic structure with a preferred orientation along ((111).) ̅ and the grain size increase with increasing concentration Cd. Data of AFM indicate that the surface of films is smooth. From SEM image observed the particles are smallest an even particle distribution on a smooth surface. The optical transition in the CuO and (Cd– doped CuO) thin films are observed to be allowed direct transition. The value of the optical energy gap decreases with increasing of (Cd) for all samples.
