Correlation between physical, optical and structural properties of sulfide glasses in the system Ge–Sb–S

Structure and optical properties of chalcohalide glasses doped with Pr3+ and Yb3+ ions

“…3a) and their assignment is in accordance with those given in papers [8,9]. The spectra of all glasses can be deconvoluted into several bands (see, e.g.…”

Structure, nonlinear properties, and photosensitivity of (GeSe_2)_100-x(Sb_2Se_3)_x glasses

“…A Raman feature peaking at ~160 cm −1 appears when Sb 2 Se 3 content reaches 40%, corresponding to Sb-Sb bond vibration in Se 2 Sb-SbSe 2 entities. Note that the Ge-based entities in this region (at ~170 cm −1 ) are dominated by the Sb-based entities, probably due to their higher polarizability, leading to masking effects, as observed in case of Ge-Sb-Te and Ge-Sb-S system [45,46]. The broad high frequency band of low intensity (~230-330 cm −1 ) also tends to disappear when increasing Sb content, meaning that its introduction induces probably a diminution of homopolar Se-Se bond in the glassy matrix.…”

Formation and properties of chalcogenide glasses based on GeS2–Sb2S3–AgI system

“…Among numerous glasses, Ge-Sb-S has been well studied and has been shown to possess good thermal stability and high nonlinear optical properties. [6][7][8] Moreover, the large glass-forming region and the compositional dependencies of various properties make it possible to tailoring material for different applications. Previous research revealed that adding AgI into sulphide glass can greatly improve the nonlinear optical properties.…”
