| 摘 要： | We study the influence of alkali oxides on the near-infrared（NIR）-emitting thermal stability of Bi-doped R2O–Si O2–B2O3–Al2O3（R = Li, Na, K） glasses below Tg. Results show that undergoing heat treatment, remarkable luminescence quenching occurs for the glasses containing Na2 O and K2 O due to the formation of Bi metallic colloids, whereas the glass with Li2 O shows much better thermal stability. These changes can be understood by the tendency of modifier cations with lower mobility and higher tightness network to restrain the transport of Bi-related NIR-emitting centers. The results provide a scientific reference for composition design of Bi-doped optical fiber. |
