Abstract
MnFe2O4:xEu3+ nanostructures were successfully fabricated via a two-step method (microemulsion combined with calcination). The as-prepared products were characterized by XRD, SEM, VSM and PL spectra analyses for the determination of the phase purity, morphology and compositions, magnetic and luminescence properties. The results showed that as-calcinated at 450 °C MnFe2O4:xEu3+ particles with the average diameter of 30–80 nm have an irregular shape. The content of Eu3+ doping has great important influence on the magnetic properties. The Ms values decreases from 42.06 to 0.69 emu/g with the increasing of Eu3+ content from 0 to 1.0 mol/L. The luminescence properties were also investigated by PL spectra. It was found that the fluorescence intensity of MnFe2O4:xEu3+ nanomaterials increased firstly and then decreased with the increasing of content of Eu3+. When the content of Eu3+ is about 0.05 mol/L, the fluorescence intensity of the products reached the maximum values.
