“…For decades, chalcogenide glass has received considerable interest owing to its excellent infrared transmittance, low phonon energy, high nonlinear refractive index, and good glass‐forming ability . For all solid‐state battery application, electrolyte materials mainly forms two kinds of conduction mechanism including ions conduction and photoelectric conduction .…”

AgI‐based Ge–Sb–S, Ga–Sb–S, and Ge–Ga–Sb–S chalcogenide glasses were designed and prepared by melt‐quenching, thereafter their thermal properties and conductive performance were comparatively investigated on the basis of their composition‐induced network structures. Glass transition in each sample was examined by DSC measurements. Results showed that the samples containing Ge had a higher thermal stability than the Ga–Sb–S–AgI sample, and the Ge–Sb–S–AgI sample obtained had the highest conductivity ion. Raman spectrum analysis was performed, and the results indicated that the [GeS4‐xIx] structural units and [SbS3−xIx] pyramids in the matrix produced effective ion transport channel for dissolved conductive Ag+ ions. In the matrix containing Ga, the [Ga(Ge)S4‐xIx] structure was consumed by part of [S3Ga–GaS3] ethane‐like units, which had no contribution to the ion transition framework. The study provided the directions for composition and structure configuration control in effective conductive chalcogenide glasses.

“…Chalcogenide glasses have excellent infrared (IR) transparency, high linear and nonlinear refractive indices, and low phonon energy, and therefore have received extensive studies in IR optics, nonlinear optics, and IR lasers . To date, many chalcogenide glass systems have been investigated and their potential applications have been evaluated.…”

In this study, a novel chalcogenide glass system, Ga–Sb–S, is reported. The glass‐forming ability, the physical properties, and the structure are investigated; and the potential applications of the glasses are evaluated. The compositions consisting of ~3%–10% Ga, ~29%–37% Sb, and ~57%–63% S can form glasses. The glasses have a wide transparent window of ~0.8–14 μm, high linear refractive indices of ~2.62–2.70 (@10 μm), high third‐order nonlinear refractive indices of ~12.4 × 10−14 cm2/W (@ 1.55 μm), low phonon energy, and large rare earth solubility. These favorable properties make them promising materials for mid‐infrared applications such as thermal imaging, nonlinear optics, and lasers.
