Gradient refractive index (GRIN) lenses have recently become a hot topic in compact imaging and achromaticity. Current research focuses on exploiting GRIN materials and upgrading the preparation technology. In this study, infrared (IR) GRIN materials were successfully prepared by spark plasma sintering of multilayer chalcogenide glass (ChGs) powders. ChGs powders were derived from the Ge20Se80‐xTex series glasses (x = 0–28 mol%) with a maximum refractive index difference (Δn) of 0.25. The similar glass transition temperatures (ΔTg < 10°C) promote efficient sintering of multilayer powders. Six‐, eight‐, and ten‐layer powders of different compositions were rapidly sintered with a thickness of 600, 300, and 200 µm per layer, respectively. Such tiny layer thickness enables the GRIN materials to exhibit nearly linear refractive index variation. Energy dispersive spectroscopy line scans well characterized the gradient variation of GRIN. The maximum deviation of the refractive index gradient from the fitted target line was only ± 0.016 for the 10‐layer GRIN. The sintered GRIN shows excellent IR transparency, which is of great interest for mid‐wave and long‐wave infrared imaging.

“…The mechanical properties of glasses and glass-ceramics were studied utilizing Vickers hardness, in torsion mode, which requires a complete separate measurement setup, or by bending, used to determine the viscoelastic properties of polymers and composites. All this investigation shows a low mechanical property what limit the application of chalcogenide glasses [1]. We made comparison between bending and torsion investigations of chalcogenide glass mechanical properties.Bending is the most common test method, because it puts the sample under a combined compression-tension load and therefore, provides the tensile moduli E' and E'' as well as the damping factor tanδ.…”

The mechanical properties of chalcogenide glasses in general are important given their application in protective coatings, infrared optics, sensors and other devices. The mechanical properties of glasses and glass-ceramics were studied utilizing Vickers hardness, in torsion mode, which requires a complete separate measurement setup, or by bending, used to determine the viscoelastic properties of polymers and composites. All this investigation shows a low mechanical property what limit the application of chalcogenide glasses [1]. We made comparison between bending and torsion investigations of chalcogenide glass mechanical properties.
