Synthesis and Characterization of Mg Doped CuO Nano Particles by Quick Precipitation Method

Undoped and Mg doped CuO wire like nano structure were successfully synthesized in PVP by using Quick Precipitation method  at a low reaction temperature (600 C) in the absence of a templates and additives. In this work, Copper acetate, PVP, NaOH, Magnesium chloride were used as copper precursor, stabilizer, accelerator and dopant (2, 5 wt %) respectively. XRD (X-ray diffraction), UV–vis spectroscopy, FE-SEM (Field Emission Scanning Electron Microscopy) and  EDAX (Energy Dispersive Analysis of X-rays ) analysis are done for structural, optical, surface morphological, and compositional analysis.  The XRD analysis revealed that there was a slight change in crystallite size which occurred with increasing concentration of Mg. The measurement of optical absorption spectra indicates that band gap shift with different percentage of Mg. The FE-SEM image reveals that the particles appear to be almost wire like in shape. The result of the EDAX confirmed the formation of CuO and CuO: Mg composition.  Due to the excellent structural and optical properties of CuO nanoparticles have wide range of applications in gas sensors, solar cell etc.
