摘要

Tm~(3+)/Al~(3+) co-doped silica glass was prepared by sol-gel method combined with high temperature sintering. Glasses with compositions of xTm~2O_3-15xAl_2O_3-(100 - 16x) SiO_2 (in mol%, x = 0.1, 0.3, 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 × 10~(-21) cm~2 at 1668 nm) and stimulated emission cross section (6.00 × 10~(21) cm~2 at 1812 nm), as well as low hydroxyl content (0.180 cm~(-1)), long fluorescence lifetime (834 μs at 1800 nm), large σ_(em) × τ_(rad) (30.05 × 10~(-21) cm~2 ms) and large relative intensity ratio of the 1.8 μm (~3F_4 → ~3H_6) to 1.46 (~3H_4 → ~3F_4) emissions (90.33) are achieved in this Tm~(3+)/Al~(3+) 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 Tm~(3+) ions was used to explain the optimum thulium doping concentration. These results suggest that the sol-gel method is an effective way to prepare Tm~(3+) doped silica glass with high Tm~(3+) doping and prospective spectroscopic properties.
