Optical properties of Er-doped chalcohalide GeGaS–CsBr glasses have been investigated as a function of Er and Ga concentrations. Nominal compositions of (Ge0.25 Ga0.10S0.65)0.9(CsBr)0.1 and (Ge0.23Ga0.12S0.65)0.9 (CsBr)0.1 glassy hosts have been chosen for this study. Up-conversion fluorescence of Er3+ ions pumped at 795 nm is reported. The simplified energy-level diagram of Er3+ ion has been used to identify the observed up-conversion fluorescence bands in visible region.
