Abstract

The spray pyrolysis technique (SPT) was used because it is simple, low cost and less equipment. Structural, morphological and optical properties of pure Co3O4 and doping 1% and 3% Zn: Co3O4 were anayzed by X- Ray diffraction (XRD), Atomic force Microscope (AFM) and UV-visible Spectroscopy. XRD indicate a polycrystalline structure  with AFM images shows that the films was discontinuous surface with spherically  grains increase from (70 to 84 nm) with increase doping from 1% to 3%. The energy gap Eg was decreased from 2.75 to 1.64 eV when doping increase. Keywords: Co3O4, Zn: Co3O4 thin films, XRD, AFM and optical characterizations.
