U skel dotovaných Pr3+ ionty byl pozorován silný emisní pás (elektronový přechod 1G4 ? 3H5) v oblasti 1340 nm.Intensita tohoto pásu se zvyšovala dotací Yb3+ iontu	luminiscence

Glasses of systems 100-y((GeS2)80(Sb2S3)20-x(PbI2)x)yPr2S3, x=0; 2; 5, 8; y=0; 0.01; 0.1; 0.5 and 99.9-z((GeS2)80(Sb2S3)18(PbI2)2)0.1Pr2S3zYb2S3, z=0.05; 0.1; 0.15) were synthesized in high purity. Their thermal and optical properties were studied. Strong luminescence band with maximum near 1340 nm (electron transition 1G4 ? 3H5) was found in Pr2S3 doped glasses. The intensity of this band was rising with doping by Yb3+ ions.	luminescence
