摘要：

In this paper, novel Fe3O4@SiO2@LaVO4:Eu2+ composites were successfully synthesized with a two-step method. Their structure and properties were analyzed and discussed. The as-synthesized nanocomposites displayed well-defined core-shell structures. The particle size of the composites is about 200 nm which consists of the magnetic core with about 180 nm in diameter and a silica shell with an average thickness of about 20 nm. Significantly, the composites exhibited a high saturation magnetization (29.40 emu g(-1)), excellent luminescence properties and high specific surface area (34.03 m(2) g(-1)), which endow the nanoparticles with great potential applications in drug targeting, bioseparation and diagnostic analysis.
