| 英文摘要 | tm3+/al3+ co-doped silica glass was prepared by sol-gel method combined with high temperature sintering. glasses with compositions of xtm(2)o(3)-15xal(2)o(3)-(100 - 16x) sio2 (in mol%, x = 0.1, 03, 0.5, 0.8 and 1.0) were prepared. the high thulium doped silica glass was realized. their spectroscopic parameters were calculated and analyzed by judd-ofelt theory. large absorption cross section (4.65 x 10(-21) cm(2) at 1668 nm) and stimulated emission cross section (6.00 x 10(-21) cm(2) at 1812 nm), as well as low hydroxyl content (0.180 cm(-1)), long fluorescence lifetime (834 mu s at 1800 nm), large sigma(em) x tau(rad) (30.05 x 10(-21) cm(2) ms) and large relative intensity ratio of the 1.8 mu m (f-3(4) --> h-3(6)) to 1.46 (h-3(4) --> f-3(4)) emissions (90.33) are achieved in this tm3+/al3+ co-doped silica glasses. according to emission characteristics, the optimum thulium doping concentration is around 0.8 mol%. the cross relaxation (cr) between ground and excited states of tm3+ ions was used to explain the optimum thulium doping concentration. these results suggest that the sol-gel method is an effective way to prepare tm3+ doped silica glass with high tm3+ doping and prospective spectroscopic properties.
