ABSTRACT
In this work, we studied deposited Cobalt- doped ZnO thin films via dip-coating
technique onto glass substrate, Zinc acetate dehydrate, cobalt acetate, 2-methoxyethanol and monoethanolamine were used as starting materials. The obtained thin films here characterized by X-ray diffraction, UV- visible absorption, Atomic force microscopy (AFM). It is found that all the thin films have good crystallinity and a preferential orientation o f crystallites along [002] axis of ZnO with wurtzite structure. The AFM have provided the information on morphology of this films where the size grain and average surface roughnes (Rms).
Key words : Thin films, ZnO, Cobalt, dip-coating, XRD, AFM, UV-Visible absorption.
