“…4(a)) with an additional contribution of Sb-(Sb,Ge) entities at 165 cm −1 . The intensity ratio of the bands at ~200 and 215 cm −1 is slightly different at a lower pressure; this qualitatively means that [GeSe 4/2 ] tetrahedra are connected by edges to a less extent [21,[33][34][35]. This analysis is basically analogous to that of glass presenting a comparable selenium deficit (Fig.…”

“…4(a)). These two bands are assigned to the symmetric stretching mode of [GeSe 4/2 ] tetrahedra connected by the corners and to the vibrations of [GeSe 4/2] tetrahedra connected by edges, respectively [21,[33][34][35]]. An addition of antimony to GeSe 2 glasses leads to an intensity ratio decrease of the bands at ~200 compared to ~215 cm −1 (Fig.…”

Abstract:The primary objective of this study is the development of transparent thin film materials in the IR enabling strong infrared absorption of organic compounds in the vicinity of metal nanoparticles by the surface plasmon effect. For developing these optical micro-sensors, heterostructures combining gold nanoparticles and chalcogenide planar waveguides are fabricated and adequately characterized. Single As 2 S 3 and Ge 25 Sb 10 Se 65 amorphous chalcogenide thin films are prepared by radiofrequency magnetron sputtering. For the fabrication of gold nanoparticles on a chalcogenide planar waveguide, direct current sputtering is employed. Fabricated single layers or hetero-structures are characterized using various techniques to investigate the influence of deposition parameters. The nanoparticles of gold are functionalized by a self-assembled monolayer of 4-nitrothiophenol. Finally, the surface enhanced infrared absorption spectra of 4-nitrothiophenol self-assembled on fabricated Au/Ge-Sb-Se thin films hetero-structures are measured and analyzed. This optical component presents a ~24 enhancement factor for the detection of NO 2 symmetric stretching vibration band of 4-nitrothiophenol at 1336 cm −1 . 232-239 (1999). 19. L. Tichý, H. Ticha, P.

“…Concerning Ge-based chalcogenide glasses, a lot of published data report on amorphous (a-) GeSe 2 structure [33][34][35][36][37] and to less extent on more complex system, such as ternary and quaternary glasses [38][39][40][41][42]. Table 2 summarizes the main features observed in the Raman scattering spectra and their attribution, according to past studies.…”

Chalcogenide glasses from (GeSe 2 ) 100-x (Sb 2 Se 3 ) x system were synthesized, with x varying from 5 to 70, in order to evaluate the influence of antimony selenide addition on nonlinear optical properties and photosensitivity. Nonlinear refractive index and two photon absorption coefficients were measured both at 1064 nm in picosecond regime using the Z-scan technique and at 1.55 µm in femtosecond regime using an original method based on direct analysis of beam profile change while propagating in the chalcogenide glasses. The study of their photosensitivity at 1.55 m revealed highly glass composition dependent behavior and quasi-photostable compositions have been identified in femtosecond regime. To better understand these characteristics, the evolution of the glass transition temperature, density and structure with the chemical composition were determined.

Note that the Vickers hardness data appearing in these seven references are merged in this plot, all of which have not intended explicitly to compositional study for the infrared lens applications out of this ternary glass system for the molded lens applications [2][3][4][5][6][7]. Specifically, even though hardness data are available across the glass-forming region, as depicted in Fig.…”

Chalcogenide glass in the ternary Ge-Sb-Se system is inherently moldable, thus being considered as a strong candidate material for use in infrared-transmitting lens applications from the viewpoint of thermal and mechanical stability. In an effort to experimentally determine compositional region suitable for the molded lens applications, we evaluate its compositional dependence of hardness. Among the constituent atoms, Ge content turns out to exert a most conspicuous correlation with hardness. This phenomenological behavior is then explained in connection with the structural evolution that Ge brings about.
