Microwave synthesis of copper oxide nanoparticles: optical and structural characterizations

Copper oxide (CuO) nanoparticles have been synthesized by microwave assisted solvothermal method using copper acetate and urea as precursors. This method gives a large scale production of CuO nanoparticles easily.The particle sizes have been obtained as, 10-14 nm. The synthesized pure copper oxide nanoparticles have been characterized by using XRD, SEM?EDAX ,UV - Visible and VSM analysis techniques. X-ray diffraction pattern (XRD) reveals single phase monoclinic structure. Scanning electron microscopy (SEM) showed the spherical morphology of as prepared CuO nanoparticles. The UVVisible absorption spectrum of CuO nanoparticles shows a strong blue shift compared to that of bulk, The antiferromagnetic (AFM) nature of CuO nanoparticles are studied using vibrating sample magnetometer (VSM).
