Abstract

Abstract: 0.2wt% Dy3+ doped and 0.2wt% Dy3+/0.5wt% Tm3+ co-doped novel GeS2–Ga2S3–PbS–CsI chalcohalide glasses were prepared and their spectroscopic properties were analyzed based on absorption (ranges from 300 to 3000nm) and emission (ranges from 1000 to 4700nm) measurements. Judd–Ofelt analyses were performed to estimate radiative transition parameters for the excited levels. Compositional dependences of near- and mid-infrared luminescences (especially the 1330, 2930 and 4320nm) excited at 808nm were investigated and discussed. These novel chalcohalide glasses may have potential uses in 1.3μm fiber-amplifiers and 2.9 or 4.3μm mid-infrared laser devices. [Copyright &y& Elsevier]
