摘要：

The energy levels associated with structural models of different valence states of Bi ions in Bi-doped silica optical fiber are investigated using the density functional theory of quantum-chemical calculation. The Bi5+, Bi3+, and Bi+ local structure models with and without Al ion are analyzed and compared with respect to their fluorescence characteristics. The result reveals that the special fluorescence effect possibly comes from Bi5+ and/or Bi3+ ions. Bi5+ ions may combine with Al ions that activate the luminescence center of Bi5+ ions. Furthermore, the distinctive fluorescence bands are efficiently generated by the coupling effect between Bi5+ and Al3+ ions. The fluorescence of Bi3+ ions may come from the Bi3+ ions with Al-free ion. Fluorescence of Bi+ ions may exist, but its contribution to the fluorescence is nominal.
