Structural and phase analysis of pure and metal ion doped mn2o3 nanoparticles prepared by microwave assisted sol-gel method

The Fe doped Mn2O3 nanoparticles were synthesized by the microwave-assisted method and synthesized samples were further annealed at 5000C and the samples were subjected to analyze structural, optical and magnetic properties. The structural properties of the nanoparticles were characterized by using X-ray diffractometry. XRD pattern revealed that the existence of Mn2O3 with cubic structure and Mn-doped Fe isa rhombohedral lattice structure. FTIR spectroscopy confirmed the formation of Fe-O stretching vibrations. The observed band positioned at 570cm-1could be due to the stretching vibration of Fe-O bonds. Energy dispersive analysis (EDAX) spectroscopy confirmed the purity, chemical composition of the FeMn2O3 nanoparticles. The structural properties were analyzed by scanning electron microscope (SEM) analysis.
