英文摘要:
In this work Er3+ doped chalcogenide glasses structurally modified by indium (In-ChG) was prepared. The mid-infrared spectroscopic properties and solubility of Er3+ in In-ChG was investigated and compared with those of gallium modified glasses (Ga-ChG). Thermal stability, mid-infrared (MIR) photoluminescence (PL), absorption spectra of both Ga-ChG and In-ChG were characterized and compared in parallel. Both the obtained MIR absorption and emission cross sections of In-ChG are higher than those of Ga-ChG. The theoretical branching ratio and decay lifetimes of I-4(11/2)-4I(13/2) transition calculated from Judd-Ofelt theory were compared with those obtained from experiments. The tested and calculated lifetime is similar and it indicates high radiative quantum efficiency. Raman spectra reveal the fact that In-ChG possess lower phonon energy than that of Ga-ChG, which might possibly give rise to the improved MIR emission. Er3+ doped In-ChG chalcogenide glass is a potential material for MIR fiber laser application. (C) 2017 Elsevier B.V. All rights reserved.
