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

摘要

Magnetic nanoparticles of Nd-Fe3O4 were prepared by hydrothermal synthesis method, using NdCl(3)6H(2)O and FeCl(3)6H(2)O 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 FeO, OH, OCO 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.
