Abstract
In this work, we reported the fabrications and characterization of Er3+-doped Ge20Ga5Sb10Se65 glasses and glass-ceramics and measured their transmission and fluorescence spectra. The results showed that, the fluorecence intensity of the glasses increased until Er3+ concentration was up to â¼1.1â¯wt% Er, and then decreased with further increasing Er3+ concentration that was due to concentration quenching effect. While it was found that the mid- and far-infrared transmission did not decrease significantly in the glasses annealed at 310â¯Â°C for a duration up to 50â¯h, seven-folded enhancement in the intensity of mid-infrared fluorescence at 2.78â¯Î¼m was observed. This demonstrated the potentials of the materials used for Er-doped amplifier and fiber laser.
