摘要：Pure superparamagnetic nano-Fe3O4 (SPMNPs) and Ln(3+) (Eu3+, Dy3+) doped SPMNPs are successfully synthesized by reverse micelle method. The structure, morphology, magnetic properties and PL properties of the samples were characterized by XRD, FT-IR, TEM, PPMS, EDS and luminescence spectrometer respectively. The influences of Ln(3+) doping amount on magnetic properties and PL properties were investigated in detail. The results show, with increasing of the Ln(3+) doping amount increasing, the morphologies and particle sizes of the doped Fe3O4 nanoparticles change, leading to saturation magnetization and coercivity changing accordingly. The change of lattice parameter and particle size was discussed based on Rietveld analysis of XRD pattern of the doped Fe3O4 nanoparticles. The coincidence of the ZFC and FC magnetization curves within the temperature range from 120.6 to 300 K, indicating that Fe3O4 nanoparticles are single domain super-paramagnetic.
