@ARTICLE{Azizi, author = {Azizi, Yahya and Aliahmad, Mousa and Gharani, Mahsa and }, title = {Experimental study optical and magnetic properties of nickel oxide nanoparticles before and after annealing}, volume = {20}, number = {0}, abstract ={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. }, URL = {http://opsi.ir/article-1-255-en.html}, eprint = {http://opsi.ir/article-1-255-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2014} }
