Geometric and optical properties of Bi/Er co-doped silica optical fiber
Source abstract
Abstract
Abstract Bi/Er co-doped silica optical fiber is investigated by using first-principle methods. Si–Bi–Er and Si–O–Bi–Er cluster models are constructed based on the interstitial Er-doped 6-membered ring (Int-Er-6MR) model for investigating the geometric and optical properties. The formation energy decreases with the increase of the Bi–Er bond length, and the Si–O–Bi–Er model is more stable than Si–Bi–Er model. Our results confirm that ~1270 nm luminescence originates from Bi+ ion and ~1530 nm luminescence stems from Er3+ ion. Besides, we discuss the possible energy transfer processes between Bi+ ion and Er3+ ion.
