Abstract :
A report is presented on the structural, electrical, optical and magnetic properties of Fe-doped ZnO nanoparticles synthesised by the solution combustion technique. Structural characterisation by X-ray diffraction confirmed the phase purity of the samples. Surface morphology studied by scanning electron microscope revealed a cubic-type shape of grains. Energy dispersive X-ray spectroscopy analysis confirmed the elemental composition. Less value of DC electrical conductivity and increased bandgap for doped ZnO from UV-Vis studies confirmed change in the defect chemistry of the ZnO matrix. However, varied synthesis process results in ferromagnetic behaviour for doped ZnO nanoparticles.
