Abstract

Composition dependences of glass-transition temperature, optical gap, photodarkening, and photoinduced volume change in xGeO₂-(100 - x)GeS₂ oxy-chalcogenide glasses have been studied comparatively. The transition temperature and optical gap are nearly constant at 0 ≤ x ≲ 80 mol %, while the photodarkening and volume expansion appear only at x ≲ 60. Implications of these results are discussed.
