Synthesis of Cu Doped NiO Nanoparticles by Chemical Method

The Cu doped NiO (NiO: Cu) nanoparticles were synthesized by co-precipitation method using NiCl2.6H(2)O, CuCl2.2H(2)O for Ni and Cu sources, respectively. Sodium hydroxide has been used as a precipitator agent. Effect of Cu doping agent on the structural and optical properties of nanostructures were characterized by XRD, SEM, AFM, spectrophotometry, FTIR and VSM techniques. XRD revealed that NiO: Cu has a FCC structure. Optical absorption spectra of the samples obtained using UV-Vis spectrophotometer shows a blue-shift when copper amount increase which indicates decreasing particle size. The study of magnetization property at room temperature shows weak ferromagnetic behavior of NiO: Cu nanoparticles. Hysteresis loops were show that magnetization increasing with Cu doping up to 13% and then with further doping decreasing. (C) 2014 JNS All rights reserved
