| 中文摘要 | the core-shell structured luminomagnetic microsphere composed of a fe3o4 magnetic core and a continuous sio2 nanoshell doped with eu(dbm)(3)center dot 2h(2)o fluorescent molecules was fabricated by a modified stober method combined with a layer-by-layer assembly technique. x-ray diffraction (xrd), fourier transform infrared spectroscopy (ftir), field emission scanning electron microscopy (fe-sem), transmission electron microscopy (tem), confocal microscopy, photoluminescence (pl), and superconducting quantum interface device (squid) were employed to characterize the fe3o4@sio2@eu(dbm)(3)center dot 2h(2)o/sio2 microspheres. the experimental results show that the microshpere has a typical diameter of ca. 500 nm consisting of the magnetic core with about 340 nm in diameter and silica shell doped with europium complex with an average thickness of about 80 nm. it possesses magnetism with a saturation magnetization of 25.84 emu/g and negligible coercivity and remanence at room temperature and exhibits strong red emission peak originating from electric-dipole transition d-5(0) -> f-7(2) (611 nm) of eu3+ ions. the luminomagnetic microspheres can be uptaken by hela cells and there is no adverse cell reaction. these results suggest that the luminomagnetic microspheres with magnetic resonance response and fluorescence probe property may be useful in biomedical imaging and diagnostic applications.
