Structural characterization of Nd-Fe₃O₄ nanoparticles prepared by hydrothermal synthesis method

ABSTRACT

Magnetic nanoparticles of Nd-Fe₃O₄ were prepared by hydrothermal synthesis method, using NdCl₃·6H₂O and FeCl₃·6H₂O as the starting materials in this paper. The structure and morphology of nanoparticles were investigated by XRD, FTIR, EDS and TEM. The results showed that, while the addition of Nd at 10% in mole ratio, resulted in the formation of Nd₂O₃ crystal peak in cubic Fe₃O₄ nanocrystallites by XRD. The absorption bands of Fe‒O, ‒OH, ‒O‒C‒O‒ and ‒CH₂‒ were accordant to the correspondent chemical groups by FTIR. The morphology of the prepared nanoparticles exhibited spherical structure and evenly distributed without agglomeration phenomenon by TEM. The elemental composition were mainly consistent with the precursor materials used in the experiment.
