ABSTRACT

Abstract : The Co doped ZnO thin films were deposited on glass substrates by dip coating method. Characterization techniques of XRD, SEM, UV-visible spectra measurements and VSM were performed to investigate the structural, optical and magnetic properties. ZnO thin films were prepared with three different growth time of 3, 4 and 5 hours at 90°C. Cobalt (Co) was doped with the prepared ZnO thin film in three different growth layer concentrations (0.01, 0.02 and 0.03mol). In magnetic studies as cobalt concentration are increase and ferromagnetic behavior increase. Key Words - ZnO thin film, Dip coating, VSM, Ferromagnetism and Cobalt.
