Investigation on the structural, optical, morphological and magnetic properties of undoped and Cd doped CuO nanoflakes

Presented here is the cadmium doped CuO nanoflakes prepared via a simple chemical precipitation method at room temperature. The results of X-ray line broadening exhibit the crystalline nature of the prepared products. X-ray photoelectron spectroscopy showed the bivalent nature of copper. The functional groups of the samples were identified by Fourier transform infrared spectroscopy. UV-Visible absorption and photoluminescence measurements reveal the optical properties of the products. The formation of CuO nanoflakes can be seen by field emission scanning electron microscopy and confirmed by transmission electron microscopy. The susceptibility measurements show the enhanced ferromagnetic behaviour of CuO with the cadmium doping.
