Synthesis and characterization of cu doped mn nanoparticles by co – precipitation method

Abstract

The Cu doped Mn nanoparticles were synthesized by Co - Precipitation method. The synthesized samples are characterized by X-ray diffraction, Scanning Electron Microscope, Fourier transform infrared spectrometer, Energy-dispersive X-Ray spectroscopy and UVV is spectrometer. The XRD studies of the sample confirmed the formation of hexagonal structure. No impurity phase was observed in the XRD. The crystallite size and lattice constants were analysed. The XRD patterns show that the average particle size is in the range of 14 nm for annealed temperature at 400°C. SEM results show both the presence of agglomeration and non agglomeration of the smaller crystallites. The EDS result exhibits the presence of Cu, Mn and O by the appearance of Mn and O peaks. This is the simple synthesis method and they are used to optical and gas sensor applications. solar cells, photocatalysis, chemical sensors,optical filters, surperionic materials, nanometer-scale switches, high-capacity cathode material in lithium secondary batteries,superconductor.
