中文摘要	in this paper, we describe the synthesis and characterization of a luminomagnetic microspheres with core-shell structures (denoted as fe(3)o(4)@sio(2)@sio(2)-tb(paba)(3)). the luminomagnetic microspheres were characterized by field emission scanning electron microscopy (fe-sem), transmission electron microscopy (tem), fourier transform infrared spectroscopy (ft-ir), vibrating sample magnetometer (vsm), and photoluminescence spectrophotometer (pl). the sem observation shows that the microsphere consists of the magnetic core with about 400 nm in average diameter and silica shell doped with terbium complex with an average thickness of about 90 nm. it has a saturation magnetization of 15.8 emu/g and a negligible coercivity at room temperature and exhibits strong green emission peak from (5)d(4) -> (7)f(5) transition of tb(3+) ions. the luminomagnetic microspheres with good magnetic response and fluorescence probe property as well as water-dispersibility would have potential medical applications, such as time-resolved fluoroimmunoassay (tr-fia), fluorescent imaging, and magnetic resonance imaging (mri).
