“…Regarding the second broad band at around 200 cm − 1 , three contributions have been reported. The vibration at 192 cm − 1 represents the Sb-Se linkage in SbSe 3/2 pyramids [17]. In accordance with Lucovsky and al., the band at 200 cm − 1 has been assigned to the ν 1 mode of corner-sharing of GeSe 4/2 [12,18,19].…”

In this paper, a detailed study to examine the influence of chalcogen S/Se mole % in the Ge 28 Sb 12 S 60 −x Se x glass system, with x = 0, 15, 30, 45 and 60, is presented that provides insight into the effect of chalcogen content on the glass network and properties. Specifically, we report results of a systematic study to evaluate the relationship between compositional variation, glass properties and dominant bonding configurations. These materials are important to applications in optics manufacturing where correlation of physical and optical properties is required to predict fabrication behavior and ultimate material performance. It has been found that the dominant bonds in the glass system change upon reaching a specific molar ratio (percentage, %) of chalcogen substitution, between 30 b x b 45 mol%, changing from Ge-Se to Sb-Se bonds as the dominant bond type. This singularity has been observed using micro-Raman spectroscopy and X-ray photoelectron spectroscopy. This effect of the dominant bond configurational change was also shown to impart changes in important physical properties including micro-hardness, thermal properties, and the glass' viscometric behavior. Results indicate that the observed dominant bond change was responsible for a constant value in the evolution of both the micro-hardness and calorimetric glass transition temperature. The viscosity was also affected by the change in dominant bond type, breaking the monotony of the viscosity evolution during the S substitution, due to the total strength of the vitreous system which does not linearly increase.

“…The vibration located at 280 cm − 1 is related to the electronic density of germanium [20]. The frequency at 300 cm − 1 is associated to F 2 asymmetric vibration modes of GeSe 4 tetrahedra [17].…”

“…In particular, ternary chalcogenide Ge-Sb-S films have drawn attention for their high non-linear optical properties and compositional dependencies of various properties either within the Ge-Sb-S film system [11,12], or within the quaternary system Ge-Sb-S-Se realized by progressively replacing sulfur with selenium [13,14]. For example, with the substitution of S by Se in the Ge-Sb-S-Se system, the glass transition temperature decreases while the density increases, making optimization of the glass composition for specific applications possible.…”

“…Here, τ 0 may be derived from fitting parameters, equated to the reciprocal value of atomic valence vibration frequency estimated from Raman spectra. Raman spectra of glasses of the given compo sitions were published earlier [13], their band maxima being positioned in the ranges 337 cm -1 for the glasses based on sulfur and 198 cm -1 for those based on sele nium. Thus, τ 0 values for glasses based on sulfur are 1.06 × 10 -13 , while for those based selenium, 1.63 × 10 -13 .…”

The concentration behavior of the thermal expansion coefficient of glasses in the system GaX 2 -GeX 2 -Sb 2 X 3 (X = S, Se) has been studied in two sections. Parameters characterizing the relaxation properties of the glasses have been calculated on the basis of the Tool-Narayanaswamy theory from experi mental temperature dependences of the thermal expansion coefficient in the softening range. Temperature dependences of the viscosity have been calculated under the assumption of equal free activation energies for the relaxation and viscous flow.
