Bifunctional Fe₃O₄@SiO₂@Eu-Polyoxometalates Nanoparticles and Study on their Magnetism and Luminescence

Abstract:

In this paper, we report the synthesis of the bifunctional Fe₃O₄@SiO₂@Eu-polyoxometalates particles. The magnetite nanoparticles (Fe₃O₄) homogeneously coated with silica spheres prepared with the Stöber method. The so-obtained Fe₃O₄@SiO₂ core/shell particles were modified by 3-aminopropyltriethoxysilane and finally grafted with the luminescent Europium -polyoxometalates. The core-shell particles were characterized by scanning electron microscopy, transmission electron microscopy, FT-IR, UV, magnetism and luminescence spectroscopy. The results indicated that the core-shell particles show both interesting luminescence and magnetic properties.
