Abstract

For rare earth doped silica-based glasses derived by sol-gel process, Al was used as a modifier in order to improve the dispersion of the rare earth ion in silica lattices, and thus, make the higher rare earth doped silica glasses without clustering possible. In this research, the influence of the ratio of Al to Nd on the fluorescence intensity and lifetime was studied in details to get the material which has a strong fluorescence intensity as well as the long fluorescence lifetime enough for integrated amplifier and laser use. Ten samples in the form of powder with different Al/Nd (in the range of 10 to 80 and different Nd (from 0.25 mole to 3 mole) concentration were prepared by sol-gel process. These powders were gotten by heating the dried gels in a furnace in air environment. The results of the fluorescence intensity and lifetime show that the Al/Nd=10 with 1 mole Nd, that is the recipe 100SiO₂:10AlO_1.5:1 NdO_1.5 has the strongest fluorescence intensity in the ten samples. But its τ_1/e is only 110μs. For 100SiO₂:20AlO_1.5:0.25 NdO_1.5, the obtained τ_1/e is 216μs without special OH movement treatment. The research results show that we need to balance the fluorescence intensity and the lifetime to choose the suitable recipe for practice use.
