Optical Properties of Nanostructure CuO Prepared by Different Stabilizing Agents

The effect of using different stabilizing agents for the synthesis of CuO nanocrystals on the morphological structure was studied. Spec grad CuCl2 and three different stabilizing agents LiOH, NaOH and kOH were used as starting materials. X-ray powder diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and UV-Visible absorption spectroscopy were used for characterizing the obtained powder samples. Surface morphologies of the obtained nanorods were found to depend on the used stabilizer. The breadth and length of the obtained nanorods were also estimated. The optical band gap of the prepared samples were found to be 2.09, 2.28, and 2.64 eV for LiOH, NaOH and kOH respectively.
