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.
