| 中文摘要 | a uniform nanolayer of europium-doped gd2o3 was coated on the surface of preformed submicron silica spheres by a pechini sol-gel process. the resulted sio2@gd2o3:eu3+ core-shell structured phosphors were characterized by x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), field emission scanning electron microscopy (fesem), transmission electron microscopy (tem), photoluminescence (pl) spectra as well as kinetic decays. the xrd results show that the gd2o3:eu3+ layers start to crystallize on the sio2 spheres after annealing at 400 degrees c and the crystallinity increases with raising the annealing temperature. the core-shell phosphors possess perfect spherical shape with narrow size distribution (average size: 640 nm) and non-agglomeration. the thickness of the gd2o3:eu3+ shells on the sio2 cores can be adjusted by changing the deposition cycles (70 nm for three deposition cycles). under short uv excitation, the obtained sio2@gd2o3:eu3+ particles show a strong red emission with d-5(0)-f-7(2) (610 nm) of eu3+ as the most prominent group.the pl intensity of eu3+ increases with increasing the annealing temperature and the number of coating cycles. |
