Abstract

A mechanism for γ-ray-induced changes in the optical properties of ternary Ge–As sulphide glasses is analysed at the microstructural level. It is shown, using IR FFT spectroscopy, that these changes are associated with chemical bond switching accompanied by coordination topological defect formation.
