| 中文摘要 | lapo4: ce3+ and lapo4: ce3+, tb3+ phosphor layers have been deposited successfully on monodispersed and spherical sio2 particles of different sizes ( 300, 500, 900 and 1200 nm) through a sol - gel process, resulting in the formation of core - shell structured sio2@ lapo4: ce3+/ tb3+ particles. x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), scanning electron microcopy (sem), transmission electron microscopy (tem), and general and time-resolved photoluminescence (pl) spectra as well as lifetimes were used to characterize the resulting sio2@ lapo4: ce3+/ tb3+ samples. the xrd results demonstrate that the lapo4: ce3+, tb3+ layers begin to crystallize on the sio2 templates after annealing at 700 degrees c, and the crystallinity increases on raising the annealing temperature. the obtained core - shell phosphors have perfectly spherical shape with a narrow size distribution, non-agglomeration, and a smooth surface. the doped rare-earth ions show their characteristic emission in the core - shell phosphors, i.e. ce3+ 5d - 4f and tb3+5d4 - f-7(j) (j = 6 - 3) transitions, respectively. the pl intensity of the tb3+ increased on increasing the annealing temperature and the sio2 core particle size. |
