“…Thus, the first sharp shoulder around 270 cm −1 can be attributed to antisymmetric stretching vibration of homopolar bonds in ETH [S 3 Ga(Ge)–Ga(Ge)S 3 ], which are mainly related to Ga contribution . Next, a lower contribution is needed around 310 cm −1 to be able to correctly fit the Raman spectra.…”

“…Thus, the first sharp shoulder around 270 cm À1 can be attributed to antisymmetric stretching vibration of homopolar bonds in ETH [S 3 Ga(Ge)-Ga(Ge)S 3 ], which are mainly related to Ga contribution. [25][26][27][28] Next, a lower contribution is needed around 310 cm À1 to be able to correctly fit the Raman spectra. Masselin et al have recently demonstrated that this contribution could be assigned to a TRI, which can be expressed as [GaS 1/3 S 3/p ] 3 , with P = 2 or 3.…”

Chalcogenide samples were synthesized by melting‐quenching method in the GeS2–Ga2S3–LiCl system to determine its vitreous domain. Different series were investigated by varying either the GeS2/Ga2S3 ratio or the molar content of LiCl. The study allows to establish that a maximum of 20 mol% of LiCl can be added in the glass composition. The glass transition and onset crystallization temperatures (Tg and Tx) and density have been determined and the thermal stability is discussed following the ΔT (Tx–Tg) parameter. The electrical conductivity of glasses increases with the LiCl content and reaches a maximum of 1.2 μS/cm at room temperature. Finally, correlations between the conductivity and the structure analyzed by Raman spectroscopy were highlighted.

“…However, the growth of both Ga2S3 and CsCl contents induces more formation of GaS4-xClx tetrahedral dispersed in the glass network [19]. Due to this change of structure, the average number of Ga-S bonds decreased to the benefit of Ga-Cl bonds.…”

Enhanced luminescence in rare‐earth‐doped chalcogenide glass–ceramics is of great interest for the potential integrated optoelectronic devices. However, fundamental mechanism on the enhancement of luminescence upon crystallization remains largely unknown. We report the fabrication and characterization of wide transmission chalcogenide glass and glass–ceramics based on the 25GeS2·35Ga2S3·40CsCl:0.3Er glass composition, and discuss the mechanism of enhanced luminescence. By monitoring the 4I9/2–4I15/2 of Er3+ transition, up‐conversion luminescence of 12 times higher was observed in glass–ceramics compared with that in base glass. Electron paramagnetic resonance (EPR) and Raman scattering spectroscopies were employed to obtain the information of selective environment of Er3+ ions and microstructural evolution with the crystallization progress. Both of them evidenced that the enhanced up‐conversion luminescence was mainly related to the local environmental evolution from a mixed chlorine‐sulfur coordination to a low phonon energy chlorine coordination in the residual glassy matrix of glass–ceramics.
