Abstract

In this paper, co-precipitation synthesized Fe₃O₄ microspheres have been encapsulated with nonporous silica and further functionalized by the deposition of Y₂O₃:Eu³⁺ phosphors through a simple co-precipitation process, realizing a hollow structured material with mesoporous, magnetic and luminescent properties. The results reveal that the material shows typical ordered mesoporous characteristics, and have monodisperse spherical morphology with smooth surface and narrow size distribution. Additionally, the multifunctional nanocomposite shows the characteristic emission of Eu³⁺ (⁵D ₀-⁷F_1-4). Magnetism measurement reveals the paramagnetic feature of the samples. Furthermore, we also compared the magnetic and fluorescent properties of solid Fe₃O₄@SiO ₂@Y₂O₃:Eu³⁺ and Fe₃O ₄@HM-SiO₂@Y₂O₃:Eu³⁺.
