• Glass Forming Region and Structure of Vitreous RS-Ga2S3 (R=Ca, Sr, Ba)

抄録

Gallium sulfide glasses were prepared in the RS-Ga₂S₃ (R=Ca, Sr, Ba) systems. Respective glass forming regions are 67.5-70.0 mol% CaS, 63.8-68.8 mol% SrS and 60.0-73.8 mol% BaS. Transmission spectra in the visible region, refractive index and glass transition and onset crystallization temperatures were measured for representative compositions of SrS- and BaS-Ga₂S₃ transparent glasses. Raman spectroscopy reveals that RS-Ga₂S₃ glasses consist of the network of GeS₄ tetrahedra due to the RS addition. The compositional dependence of molar volume indicates a plateau region at 65-70 mol% RS in SrS- and BaS-Ga₂S₃ glasses. The morphology of sulfur complex anions in RS-Ga₂S₃ glass melts is discussed using the sulfur-to-gallium ratio as a variable parameter. The combined results suggest that well-developed glass networks are formed near 66.7 mol% RS (S/Ga=2.5) in the SrS- and BaS-Ga₂S₃ systems.
