| 中文摘要 | x-1-y(2)sio(5):eu3+ and x-1-y2sio5:ce3+ and/or tb3+ phosphor layers have been coated on nonaggregated, monodisperse, submicron spherical sio2 particles by a sol-gel process, followed by surface reaction at high temperature (1000 degrees c), to give core/shell structured sio2@y2sio5:eu3+ and sio2@y2sio5:ce3+/tb3+ particles. x-ray diffraction (xrd), field emission scanning electron microscopy (fesem), tem, photoluminescence (pl), low voltage cathodoluminescence (cl), and time-resolved pl spectra and lifetimes are used to characterize these materials. the xrd results indicate that x-1-y2sio5 layers have been successfully coated on the sur- face of sio2 particles, as further verified by the fesem and tem images. the pl and cl studies suggest that sio2@y2sio5:eu3+, sio2@y2sio5:tb3+ (or ce3+/tb3+), and sio2@y2sio5:ce3+ core/shell particles exhibit red (eu3+, 613 rim: d-5(0)-f-7(2)), green (tb3+, 542nm: d-5(4)-f-7(5)), or blue (ce3+, 450nm: 5d-4f) luminescence, respectively. pl, excitation, emission, and time-resolved spectra demonstrate that there is an energy transfer from ce3+ to tb3+ in the sio2@y2sio5:ce3+,tb3+ core/shell particles. |
