Bulk chalcogenide glasses, Ge based sulphides Ge25Ga10S65 and (GeS2)80(Ga2S3)20, and tellurides Ge20Se80−xTex, for x from the interval 0,15, and those doped with Er, Pr and Ho ions have been prepared by direct synthesis and investigated by optical transmission and low temperature PL spectroscopy. The efficiency of 4f–4f transitions in Ge–Se–Te:RE glasses is steadily decreasing with increasing Te content. A pronounced re-absorption of the host glass luminescence is observed in telluride glasses doped with Pr and Er.
