In the last few decades, chalcogenide glasses have received considerable attention as infrared-transmitting materials for infrared systems such as surveillance cameras. In this review, two chalcogenide glass groups are introduced, where germanium sulfide and gallium sulfide are used as the main components. Germanium sulfide glass systems comprise Ge-Ga-Sb-S and Ge-Sb-Sn-S systems, whereas gallium sulfide glass systems comprise Ga-Sb-AS systems (A = Sn, CsX, (X = Cl, Br, I)). Although these glass systems are free from selenium and arsenic which are commonly used in chalcogenide glasses, they have wide glass-forming composition regions. The glasses are thermally stable against crystallization and can be shaped by molding. Germanium-free gallium sulfide-based glasses are also transparent up to a wavelength of ~13 μm, and their optical window almost covers the atmospheric windows. In addition to the glass-forming regions, the fundamental properties of these glasses including the transmission spectra and refractive indices are presented in this review.

“…The incorporation of metal halides into chalcogenide glassy matrix allows new functional materials to be obtained with the unique optical and electrical properties such as wide transmission range extended in the both infrared and visible spectral regions, high linear and nonlinear refractive indices, low phonon energies, photosensitivity, and high ionic conductivity. [ 1–4 ] These results make the chalcohalide glass systems promising candidates for application in infrared optical instruments, electronic devices, and chemical sensors. [ 5–8 ] However, the systematic studies of MY–Ga 2 S 3 –GeS 2 glasses as a function of the cation nature, Ga 2 S 3 /GeS 2 fraction, and MY content are limited.…”

Glass‐forming region, macroscopic properties, and electrical conductivity changes are systematically studied in the MY–Ga2S3–GeS2 systems, where M = Na, K, Rb and Y = Cl, Br, I, as a function of alkali concentration, MY chemical composition, and Ga2S3/GeS2 ratio using two composition lines: series A – (MY)x(Ga2S3)0.2–0.2x(GeS2)0.8–0.8x and series B – (MY)x(Ga2S3)0.2 + 0.2x(GeS2)0.8−1.2x. Glasses of series B are characterized by higher maximum MY concentration, increasing with the cation radius up to 66.7 mol% in case of RbCl. The halide nature is found to be less significant for the vitrification ability. The density of samples varies monotonically between the two end‐members of each series. Glass transition temperature decreases with increasing alkali concentration, ranging from 426 °C (x = 0) to 237 °C for (RbCl)67(Ga2S3)33 sample. The conductivity of MY–Ga2S3–GeS2 glasses decreases with increasing cation radius. The Ga2S3/GeS2 ratio and the halide nature affect the conductivity weakly.
