| 英文摘要 | tb3+ single-doped sio2 (sio2:tb3+) and tb3+, ag co-doped sio2 (sio2:tb3+-ag) nanostructured luminescent materials were prepared by a modified stober method. their microstructure and optical property were investigated using scanning electron microscopy, ultraviolet visible absorption and photoluminescence spectrophotometry. results show that the samples are composed of well-dispersed near-spherical particles with a diameter about 50 nm, the highest fluorescence intensity is obtained when the doping concentration of tb3+ is 4.86 mol%, the corresponding internal quantum efficiency is 13.6% and the external quantum efficiency is 8.2%. the experimental results indicate that ag nanoparticles can greatly enhance the light absorption at 226 nm and the light emission at 543 nm of sio2:tb3+-ag, and the fluorescence lifetime reduces with increasing ag concentration in sio2:tb3+-ag. additionally, the present results indicate that fluorescence enhancement is attributed to the local field enhancement and the increased radiative decay rates induced by ag nanoparticles.
