OPTICAL CHARACTERIZATIONS OF Zn-Doped CuO NANOPARTICLES

In this work we evaluate structural and optical properties of Zn-Doped CuO nanoparticles grown by microwave assisted solvothermal method. The formation of Zn-Doped CuO nanoparticles were confirmed by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and UV-Visible spectroscopy. The average particle size have been found to be about 40 to 80 nm , The SEM image showed that the prepared product consists of spherical nanoparticles with narrow size distribution. The UV-Visible spectrum of Zn doped-CuO nanoparticles shows a strong blue shift compared to that of bulk and also shows the band edgeabsorption peak and is found to be at 350 nm. The obtained band gap value is 2.65 eV for Zn-Doped CuO nanoparticles.
