“…The addition of Ga (Ga 2 S 3 ) (I=0.138 for Ga-S bonds) can enhance RE solubility. A similar effect of Ga addition was also observed in covalent As-S glasses [11] (I=0.039 for As-S bonds). High RE solubility was also confirmed in GaLaS glasses [12] (I=0.422 for La-S bonds).…”

“…Currently, RE doped chalcogenide glass hosts which can be drawn into fibers are mainly based on As-S, Ge-As(Sb)-Ga-S(Se), and Ga-La-S glasses, according to the reports [8][9][10][11][12] . The As 2 S 3 glass can be easily prepared and drawn into fibers, but its maximum RE solubility is less than 300ppm in fiber drawing and its working temperature is relatively low due to its low transition temperature (T g ).…”

“…Silica glass ampoules are commonly used as the container in chalcogenide glass melting . As discussed in our previous work, the chalcogenide glass surface was found to be contaminated by Dy, Si and [O] in Dy 3+ (DyCl 3 )‐doped Ge 16.5 As 19– x Ga x Se 64.5 glasses, for x = 3, 10, proposed due to corrosion of the silica ampoule by the DyCl 3 additive.…”

Dy³⁺‐Doped Selenide Chalcogenide Glasses: Influence of Dy³⁺ Dopant‐Additive and Containment

This work reports on process-induced impurities in rare-earth ion: Dy 3+ -doped selenide chalcogenide glasses, which are significant materials for active photonic devices in the mid-infrared region. In particular, the effect of contamination from the silica glass ampoule containment used in chalcogenide glass synthesis is studied. Heat-treating Dy-foil-only, and DyCl 3only, separately, within evacuated silica glass ampoules gives direct evidence of silica ampoule corrosion by the rare-earth additives. The presence of [Ga 2 Se 3 ] associated with [Dy] on the silica glass ampoule that has been contact with the chalcogenide glass during glass melting, is reported for the first time. Studies of 0-3000 ppmw Dy 3+ -doped Ge 16.5 As 9 Ga 10 Se 64.5 glasses show that Dy-foil is better than DyCl 3 as the Dy 3+ additive in Ge-As-Ga-Se glass in aspects of avoiding bulk crystallization, improving glass surface quality and lowering optical loss. However, some limited Dy/Si/O related contamination is observed on the surfaces of Dy-foil-doped chalcogenide glasses, as found for DyCl 3 -doped chalcogenide glasses, reported in our previous work. The surface contamination indicates the production of Dy 2 O 3 and/or [Si-O-Dy=]-containing particles during chalcogenide glass melting, which are potential light-scattering centers in chalcogenide bulk glass and heterogeneous nucleation agents for a-Ga 2 Se 3 crystals.

“…This goal can be realized in Ga‐modified (or alternatively In‐modified) glassy networks possessing efficient charge‐compensation ability for dopants, as RE ions tends to clusterize in pure undoped ChG matrix . However, the Ga additions can provoke intensive devitrification processes, thus essentially restricting possibilities for glass modification . It was shown that in case of As 2 Se 3 glass it is possible to introduce just up to 3 at.% of Ga without crystallization .…”

The influence of Sb on glass‐forming ability of Ga‐containing As₂Se₃ glasses

Effect of As to Sb substitution on glass-forming ability of As 2 Se 3 glass under Ga additions was comprehensively studied using optical spectroscopy in visible and IR regions, differential scanning calorimetry, X-ray diffraction as well as Raman scattering techniques. The crystallization processes enhanced by Ga additions to As 2 Se 3 glass were significantly suppressed under such As to Sb substitution. Following conventional synthesis, it was possible to substitute up to 50% of As by Sb within Ga y (As 0.40Àx Sb x Se 0.60 ) 100Ày cut-section without essential impact on glassy state, thus improving optical properties in the IR region by lowering the phonon energy. In the case of Ga y (As 0.28 Sb 0.12 Se 0.60 ) 100Ày cut-section, up to 8 at.% of Ga can be introduced without crystallization, whereas in case of Ga y (As 0.40 Se 0.60 ) 100Ày system, glass-forming ability is limited just up to 3 at.% of Ga. The prepared Ga 5 (As 0.28 Sb 0.12 Se 0.60 ) 95 glass composition was shown to be the richest in Ga keeping its vitreous state, good optical and thermodynamic properties allowing further rare-earth doping and fiber drawing.
