| 中文摘要 | spherical sio2 particles have been coated with rare earth oxide layers by a pechini sol-gel process, leading to the formation of core-shell structured sio2@re2o3 (re = rare earth elements) and sio2@gd2o3:ln(3+) (ln = eu, tb, dy, sm, er, ho) particles. x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), transmission electron microscopy (tem), photoluminescence (pl), and cathodoluminescence spectra as well as lifetimes were used to characterize the resulting sio2@re2o3 (re = rare earth elements) and sio2@gd2o3:ln(3+) (eu3+, tb3+, dy3+, sm3+, er3+, ho3+) samples. the obtained core-shell phosphors have perfect spherical shape with narrow size distribution (average size ca. 380 nm), smooth surface and non-agglomeration. the thickness of shells could be easily controlled by changing the number of deposition cycles (40 nm for two deposition cycles). |
