Study the properties of spin-coated Co-doped ZnO (CZO) thin Film

Abstract


Co doped ZnO (COZ) nanoparticles were prepared by spray pyrolysis technique followed by annealing at three different temperatures. XRD, UV- Vis spectroscopy, Photoluminescence (PL) studies, Scanning electron microscopy (SE), and vibrating sample magnetometry (VSM) studies were made to analyze the structural, optical and magnetic properties. XRD pattern confirmed the improved crystallinity after annealing and the formation of hematite phase. A UV-visible spectrum indicates that the nanoparticles exhibit the blue shifting of λmax with the increase of crystallite size. Band gap of the COZ nanoparticles were found to increase with the annealing temperature. A VSM study reveals the superparamagnetic nature of the as deposited and annealed COZ nanoparticles with a strong saturation magnetization (Ms).
