Raman and infrared spectroscopic studies of GeGaAg sulphide glasses
TL;DR: In this paper, the structural arrangement of these glasses is studied as a function of the composition in the ternary glass-forming region, and the vibrational assignment is made mainly in terms of bridging and non-bridging sulphur in the vitreous network.

Scattering losses in optic fiber materials. II. Numerical estimates
TL;DR: In this paper, numerical estimates have been obtained for density fluctuation, Raman, and concentration fluctuation scattering losses in a number of materials which are under consideration as candidates for ultralow loss fiberoptic applications.
Journal ArticleDOI
Compositional variation in the structure of Ge-S glasses
TL;DR: X-ray photoelectron spectroscopy (XPS), and X-ray fluorescence (XRF) and Raman spectroscopies have been used to characterize the structure of Ge-S binary glasses in the compositional range 57-90 at.% S, together with evaluating the valences of Ge and S as mentioned in this paper.

Glass formation and properties of chalcogenide systems XXXII. RDF studies on the structure of vitreous Ge2S3 and Ge2Se3
TL;DR: In this article, the structure of the bulk glasses GeS2 with the aid of X-ray diffraction measurements and RDF calculations are reported which are supported by pair function calculations based on a wire model constructed by hand which has been approximated in three steps in order to guarantee the isotropy criteria and the experimental density preferentially taking into consideration the bond parameters of the high temperature modification of crystalline GeS 2.

Properties and Structure of Glasses in the System Ge‐S
Yoji Kawamoto,Shoji Tsuchihashi +1 more
TL;DR: In this paper, the properties of these glasses, e.g. ir absorption spectra, thermal expansion, extraction of S8 molecules with CS2, Vickers hardness, density, and optical absorption, led to the conclusion that the structures of glasses in the two regions differ.

Study of the optic modes of Ge 0.30 S 0.70 glass by infrared and Raman spectroscopy
TL;DR: In this paper, a study of the room-temperature infrared reflectance and Raman spectra has been made on a room temperature glass, and the dominant features of the two spectra are complementary with respect to frequency, and can be understood in terms of a molecular model in which the Ge atoms are fourfold coordinated and S atoms twofold coordinated.
