Interstitial BiO molecule as a center of broadband IR luminescence in bismuth-doped silica glass
V. O. Sokolov, V. G. Plotnichenko, E. M. Dianov
IR luminescence and absorption in bismuth-doped silica glass-core fibers observed recently (see [arXiv:1106.2969v1 [physics.optics]) are argued to be caused by transitions in inter…
