The study of Bismuth (Bi)-doped silica fibers has been performed by using thermally stimulated luminescence. The thermoluminescence peaks have been spectrally resolved in order to observe the effect of codopants on Bi luminescence. A new peak around 625K was observed for the first time in Bi-doped Al-Ge-silicate fibers. This peak is believed to be due to Bi-active centers, and was only observed in Bi-doped samples co-doped with both Al and Ge.
