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. [ABSTRACT FROM AUTHOR]- Published
