| 中文摘要 | spherical sio2 particles have been coated with yvo4:dy3+/sm3+ phosphor layers by a pechini sol-gel process, leading to the formation of core-shell structured sio2@yvo4:dy3+/sm3+ particles. x-ray diffraction (xrd), fourier-transform ir spectroscopy, field emission scanning electron microscopy (fe-sem), transmission electron microscopy (tem), photoluminescence (pl) spectra as well as lifetimes were used to characterize the resulting sio2 @yvo4:dy3+/sm3+ core-shell phosphors. the obtained core-shell phosphors have perfect spherical shape with narrow size distribution (average size ca. 300 nm), smooth surface and non-agglomeration. the thickness of shells could be easily controlled by changing the number of deposition cycles (20 nm for one deposition cycle). the core-shell particles show strong characteristic emission from dy3+ for sio2@yvo4:dy3+ and from sm3+ for sio2@yvo4:sm3+ due to an efficient energy transfer from yvo4 host to them. the pl intensity of dy3+ and sm3+ increases with raising the annealing temperature and the number of coating cycles. |
