The structural properties of the prepared compounds have been investigated using X- ray diffraction (XRD). The mean particle size was calculated using Debye-Scherer equation. Optical properties of the prepared nanostructures have been investigated using ultraviolet-visible (UV-Vis) and Fourier transform infrared (FTIR) spectroscopies. The surface morphology of the prepared nanostructure has been investigated using scanning electron microscopy, which shows formation of spherical cobalt oxide nanoparticles }, URL = {http://opsi.ir/article-1-525-en.html}, eprint = {http://opsi.ir/article-1-525-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2015} }
