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.
The pure and various metals (Ni and Ba) doped Cadmium Sulphide (CdS) nano particles were successfully synthesized by chemical co-precipitation method using analytical grade Cadmium Chloride and Sodium Sulphide chemicals. The prepared samples were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Optical absorption (UV-Vis) studies. The XRD results showed that the all prepared samples were polycrystalline with hexagonal structure. The peaks were identified and compared with JCPDS (File No. 89-2944) values. From the SEM studies, the particles agglomerations are decreased by the addition of metal dopants and the average grain size of the particles are found in the range 500 nm. The optical properties have been characterized. The obtained band gap values are 2.56 eV, 2.54 eV, 2.35 eV and 2.48 eV. The band gap is reduced and the crystallization is increased in the Ni and Ba doped CdS nano particles are more suitable for fabrications of Opto electronic studies.
