Al^3＋ is considered as a beneficial activator for Yb^3＋-doped glass. However, the experimental result shows that the addition of Al^3＋ results in the transformation from Yb^3＋ to Yb^2＋ and the improvement in the photon luminescence of Yb^2＋. These characteristics indicate the role of Al^3＋ in Yb^3＋-dooed glass.展开更多
