Abstract: The nanocrystals Mn₃O₄ powder have been prepared using [Bis(salicylidiminato)manganese(II) ] as precursor. Effect of oleylamine and triphenylphosphine on particle morphology has been investigated. Transmission electron microscopy (TEM) analysis demonstrated nanocrystals Mn₃O₄ with an average diameter of about 20 nm. The structural study by X-ray diffraction (XRD) indicates that these nanocrystals have pure tetragonal phase. The phase pure samples were characterised using X-ray photoelectron spectroscopy (XPS) for both Mn 2p and Mn 3s levels. The values of binding energies are consistent with the relative values reported in the literature.

Keywords: Mn3O4; synthesis; monodisperse nanocrystals; manganese oxides; nanotechnology.
