| 中文摘要 | europium-doped nanocrystalline gdvo4 phosphor layers were coated on the surface of preformed submicron silica spheres by sol-gel method. the resulted sio2@gd0.95eu0.05vo4 core-shell particles were characterized by x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy (fesem), energy-dispersive x-ray spectra (eds), transmission electron microscopy (tem), photoluminescence (pl) spectra, low voltage cathodoluminescence (cl), time resolved pl spectra and kinetic decays. the xrd results demonstrate that the gd0.95eu0.05vo4 layers begin to crystallize on the sio2 spheres after annealing at 600 c and the crystallinity increases with raising the annealing temperature. the obtained core-shell phosphors have spherical shape, narrow size distribution (average size ca. 600 nm), non-agglomeration. the thickness of the gd0.95eu0.05vo4 shells on the sio2 cores could be easily tailored by varying the number of deposition cycles (50 nm for four deposition cycles). pl and cl show that the emissions are dominated by d-5(0)-f-7(2) transition of eu3+ (618 nm, red). |
