Synthesis of γ-Fe2O3, Fe3O4 and copper doped Fe3O4 nanoparticles by sonochemical method

Nanoparticles of undoped and copper doped with Fe3O4 of three concentrations (0.5, 1.0 and 1.5) are synthesized by sonochemical method. Structural, optical and morphological properties of these compounds were studied. Fe2+/Fe3+ ratio is found to be 2.36. Crystalline structure, lattice parameters, su...
