Sulphide glasses of GeGaS and GeGaAsS systems doped with rare earth ions, particulary the systems Ge_0.25Ga_0.1-xS_0.65Pr_x and Ge_0.25Ga_0.05-xAs_0.05S_0.65Pr_x with x=500, 1000, 3000, 6000 wt.ppm have been prepared. Synthesised material systems have been characterised by Raman and low-temperature photoluminescence spectroscopies. The optimal Pr concentration has been found to be around 1000 wt.ppm. The appearance of temperature induced radiative transitions have been observed on GeGaS:Er samples.
