INVESTIGATION OF STRUCTURAL AND MAGNETIC PROPERTIES OF MOLYBDENUM DOPED ZnO NANOSTRUCTURES PREPARED BY MICROWAVE-ASSISTED WET CHEMICAL METHOD

The Molybdenum doped zinc oxide nanostructures (Mo-x = 1 wt%, 3 wt%, 5 wt% and 7 wt%) were synthesized by wet chemical synthesis method by using microwave irradiation for 15 minutes. The present work focuses on the effect of molybdenum doping on microstructural and magnetic properties of the ZnO nanomaterials. The prepared samples were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and vibrational sample magnetic spectroscopy (VSM). The XRD pattern reveals that Mo is substituted in the ZnO lattice. The SEM micrograph of pure ZnO shows the presence of dumbbell-shaped nanostructures and it's having average length 4.75 mu m and diameter 2.65 mu m which is well matched with TEM results. The SEM and TEM micrographs of Mo-doped ZnO samples reveal that the presence of a spherical shaped particle with an average size of 29nm. The presence of Mo and ZnO compounds were confirmed by EDAX spectrum. The magnetic properties of prepared samples were carried out by VSM studies and Mo-doped ZnO nanostructures exhibit the ferromagnetic behaviour at room temperature.
