Magnetic and luminescent properties of Fe3O4@Y2O3:Eu3+ nanocomposites: "

Abstract

The multifunctional Fe₃O₄@Y₂O₃:Eu³⁺ nanocomposites were prepared by a facile solvothermal method with Fe₃O₄ nanoparticles as the core and europium-doped yttrium oxide (Y₂O₃:Eu³⁺) as the shell. It is shown that Fe₃O₄@Y₂O₃:Eu³⁺ nanocomposites have a strong photoluminescence and special saturation magnetization Ms of 6.1 emu/g at room temperature.
The effects of the magnetic field on the luminescence intensities of the nanocomposites are being discussed. The multifunctional
nanocomposites with magnetic resonance response and fluorescence probe properties may be useful in biomedical applications,
such as cell separation and bioimaging.
