Mid-IR impurity absorption in As₂S₃ chalcogenide glasses doped with transition metals

摘要

Room temperature IR impurity absorption spectra in 1 4000 7000 cmud( 4.1 - 25um ) region for chalcogenide glasses of As₂S₃ doped with chromium (0.5,ud1 wt.%) and manganese (0.1, 1, 2, 5 wt.%) have been studied. The effects of chromiumudand manganese impurities on the transmission spectra are discussed.
