Sulphide glasses of GeGaS and GeGaAsS systems doped with rare earth ions are promising materials for various photonic applications. 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 and characterised by chemical and X-ray analysis, scanning electron microscopy, light scattering, Raman and low-temperature photoluminescence spectroscopies. The optimal Pr concentration has been found to be around 1000 wt. ppm.
