| 中文摘要 | a sol-gel technique was used to prepare gd2ti2o7:eu3+-coated submicron silica spheres (sio2@gd2ti2o7:eu3+). the resulted sio2@gd2ti2o7:eu3+ core-shell particles were characterized by x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy (sem), energy-dispersive x-ray spectra (eds), transmission electron microscopy (tem), photoluminescence (pl) spectra, as well as kinetic decays. the xrd results demonstrate that the gd2ti2o7:eu3+ layers begin to crystallize on the sio2 spheres after annealing at 800 degrees c and the crystallinity increases with raising the annealing temperature. the obtained core-shell phosphors have perfect spherical shape with narrow size distribution (average size similar to 620 nm), non-agglomeration, and smooth surface. the thickness of the gd2ti2o7:eu3+ shells on the sio2 cores could be easily tailored by varying the number of deposition cycles (60 nm for four deposition cycles). under the irradiation of 310 nm ultraviolet, the sio2@gdti2o7:eu3+ samples show strong emission of eu3+. |
