Magnetic, optical and structural characterization of ZnO:Co; ZnO:Fe thin films

Co-doped ZnO and Fe-doped ZnO diluted magnetic semiconductor films were prepared on glass substrates by chemical spray pyrolysis (CSP) method. Synthesized ZnO:Co and ZnO:Fe thin films by CSP method were compared to thin film properties. Optical analysis of the synthesized thin films was examined by spectral absorption and transmittance measurements using UV-Vis double beam spectrophotometer technique and Photoluminescence (PL) spectroscopy. Structural characterizations of the thin films were examined by using X-ray diffraction (XRD), Raman Analysis, field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX) and atomic force microscopy (AFM) techniques, respectively. Magnetic properties of the films investigated by Vibrating sample magnetometer (VSM) measurements and magnetization measurements of thin films were compared.VSM measurements of ZnO:Co and ZnO:Fe thin films showed that ferromagnetic behavior for each thin films.
