Comparative study on structural, morphological, and optical properties of MS/Fe3O4 nanocomposites and M-doped Fe3O4 nanopowders (M = Mn, Zn).

ABSTRACT: In the present work, the un-doped, M-doped magnetite (Fe₃O₄); (M = Mn, Zn), and MS/Fe₃O₄ composite nanopowders with a cubic spinel-type structure and average crystallite size range from 8.30 to 12.33 nm were synthesized by co-precipitation method. The FESEM images revealed the shape of particles are spherical with a grain size in the range of 33.44-49.77 nm. Through the analysis of reflectance data using Tauc's model, the direct band gap energies of 2.98 eV, 2.93 eV, 3.01 eV, 2.85 eV, and 2.95 eV were determined for Un-doped Fe₃O₄, Mn-doped Fe₃O₄, Zn-doped Fe₃O₄, MnS/Fe₃O₄ composite, and ZnS/Fe₃O₄ composite NPs respectively.
