Abstract
ABSTRACTThis work presents optical properties of Zn and Mn co-doped CFO (Co0.6Zn0.4Mn0.3Fe1.7O4) films deposited on Si and Pt coated Si substrates by spin coating technique. X-ray diffraction pattern of the films exhibited spinel cubic structure with polycrystalline phase. Optical characteristics of the CZFMO films are studied using photoluminscence and UV-visible spectroscopy. With the rise in annealing temperature, quenching in PL emission was observed for films grown on silicon; whereas a marginal enhancement in emission was observed for films deposited on the Pt / Si substrate. Optical band gap of the films are found to vary between 2.3 – 2.7 eV range.
