摘要：
We report silica fiber with trivalent bismuth (Bi3+) in first-principles calculations. The influences of members of “Si–O–Si” rings are considered to study atomic structures, frontier molecular orbital and optical properties of Bi-doped optical fiber. Our results reveal that the luminescence of Bi3+-doped optical fiber is the result of a combination of Bi3+ ions and silica matrix. Different ring structures affect the luminescence properties, which explained why Bi3+-doped silica fiber usually cover a broad spectral range from the UV to visible light.
