Synthesis and characterization of Na doped cupric oxide (CuO) nanoparticles

In the last decade, the developments of nano size materials of metal and metal oxide particles are intensively pursued because of their prominence in different fields of applications. Monoclinic Copper oxide nanoparticles have received appertain due to its wide range of applications in interesting size-dependent chemical properties and due to their interactive properties such as large surface-to-volume ratio and distinctive electronic and optical properties. Understanding of doping and conduction mechanism in this material are, however still intricate and challenging. Pure Cupric oxide nanoparticles and Na doped CuO are synthesized by the solution combustion method. Evolution of structure of these nanoparticles was studied by X-ray diffraction (XRD). Scanning Electron Microscopy (FESEM) was used for morphological study of CuO nanoparticles. AC impedance spectroscopy, a powerful technique to inquire the electrical properties of nano crystalline semiconductors is used to probe the dynamics of the mobile and bound charges in the bulk or interfacial region of CuO nanocrystals.
