Abstract: (5298 Views)
In this work, nickle oxide nanoparticles were prepared by using the preciptitation method. Samples with different techniques such as UV-Vis, FT-IR, VSM and XRD were charactrized. XRD results for the annealed sample shows the crystalline peaks, but as synthesized sample is amorphous. the VSM results show antiferomagnetic and super-paramagnetic properties before and after annealing the sample, respectively. the UV-Vis spectra show that band gap energy is increasing with decreasing the particles size.
