Synthesis and characterization of different percentage (Fe2+) doped copper oxide (CuO) NPs prepared by chemical method

Abstract

In the last decade the metal oxide NPs are the promising applications in the research field. The lot of methods to available in the synthesis of NPs, but co-precipitation method is very simple, low cost and environmental friendly. The different percentage (Fe 2+ ) doped copper oxide (CuO) NPs prepared by co-precipitation method. XRD pattern confirms the samples are crystalline in monoclinic structure identified by the JCPDS Card. No (80-0076). The doping concentration increases the crystalline size also decreases. CuO NPs based functional groups are identified from FTIR spectra. UV-Vis Spectroscopy the Fe doped CuO has a band gap is determined in the range of 3.57 to 3.62 eV. The Pl emission spectra revealed a blue shift after introducing Fe into CuO structure, from these studies is better for the preparation of CuO nanoparticles. SEMthe surface morphology of the as prepared CuO nanoparticles has identified by SEM studies the indefinite and closely packed grain is observed. The EDAX spectra showed presence copper, Fe and oxygen atoms.
