Up-conversion fluorescence in Er-doped chalcogenide glasses based on GeS2–Ga2S3 system

EPR of γ-induced defects and their effects on the photoluminescence in the glasses of the Ag0.05Ga0.05Ge0.95S2–Er2S3 system

“…It was shown in Tverjanovich et al (2001Tverjanovich et al ( , 2003 that the intensity of the anti-Stokes PL depends substantially on the position of the edge of fundamental absorption of the glass matrix formed in the GeS 2 -Ga 2 S 3 -Er 2 S 3 system and is similar to what was investigated in this work. The PL intensity increases if the fundamental absorption edge of the glasses shifts to the high-energy side, and vise versa.…”

Influence of NaX (X=I or Cl) additions on GeS2–Ga2S3 based glasses

“…Even this pseudobinary system is already interesting thanks to its intrinsic properties, it is more pleasing because of the large possibility to be doped for optical or conductivity applications. For example, they possess a high solubility of rare-earth ions and consequently they are very promising as host glass matrix in the fluorescence material domain in the near-and mid-infrared regions [4][5][6][7]. Also, the possibility to add alkali halide in this system to extend the visible and infrared transparency range and to affect crystallization behavior by self-nucleating and nucleating agent was also used to promote phase separation and bulk nucleation [8,9].…”

Nd Solubility in RS-Ga2S3 (R=Sr, Ba) Glasses

“…15) Extrinsic factors aecting RE solubility are melting conditions, e.g., temperature, time, atmosphere and the cooling rate of melts. Raw materials for rareearth constituents in nal sulde glasses are elemental, 16) sulde 8),10)13) and halide 16) forms. According to previous studies, 16),17) rareearth elements and chlorides can be dissolved with relativelyhigh concentrations.…”
