چکیده انگلیسی
Monovalent bismuth-related centers in pure silica optical fiber are calculated by using first-principle methods. Transition energy levels of three different structural models are investigated on the basis of the time-dependent density functional theory (TDDFT). Compared with the experimental data of near-IR luminescence, our calculated results suggested that luminescence near 1492â¯nm is likely caused by SiOBi configuration; and luminescence at 1147â¯nm and 1403â¯nm may be caused by interstitial Bi2O molecule. Moreover, SiBi configuration, which might be the origin of the luminescence near 1629â¯nm, is difficult to directly form because of its relatively high formation energy.
