Synthesis, Optical and Electrical Properties of ZnFe2O4 Nanocomposites

ZnFe2O4 nanocomposites have been prepared by a simple co-precipitation method. The prepared samples were characterized by Scanning Electron Microscopy (SEM), Powder X-ray Diffraction (XRD), Energy Disperse X-ray Analysis (EDX), Transmission electron microscopy (TEM) and UV-visible absorption spectral techniques. Conductivity measurements show a transition from ferrimagnetism to paramagnetism. The enhancement in fluorescence spectra shows that there is an electronic transition to an exciting level. In UV-Vis spectra, the peak observed at 647nm indicates ZnFe2O4 nanocomposites are a photoactive compound. The above results suggest that these nanomaterial
