“…The intensity of this absorption increased with an increase in the relative concentration of GeS 2 in glasses ( Figure 2 B). With a significant increase in the relative content of Sb 2 S 3 in glasses (compositions 1 and 2 ), a peak appeared in the region of 16.1 μm, which, apparently, was due to the presence of Sb-O bonds (the Raman spectrum of crystalline Sb 2 O 3 was characterized by an intense band in the region of 647 cm −1 (15.5 μm) and a weak band at 592 cm −1 (16.9 μm)) [ 30 ]. Impurity Ga-O bonds (14.7 μm) [ 31 ] can also be presented in the glasses.…”

The physicochemical, optical, and luminescent properties and structures of glasses of the Ga2S3-GeS2-Sb2S3:Pr system have been studied in a wide range of concentrations of the main components in order to reveal their correlation with the composition. According to the calculations using the Judd–Ofelt theory, glasses with a high content of Sb2S3 should provide the highest luminescence efficiency of Pr3+ ions. However, this result is leveled by enhancing the concentration quenching effect, followed by an increase of the Sb2S3 content in the glasses. The introduction of Pr leads to a significant increase in the fraction of Sb-Sb, Sb-Ge, Ge-Ge bonds in glasses enriched with Sb2S3 and GeS2. In the cases of the glasses enriched with Ga2S3, this effect was not observed, apparently because Ga promotes the formation of three-coordinated sulfur atoms.
