Radiation-induced physical ageing of the structure of an arsenic–selenide glass

The effect of γ-irradiation (Co60 sources) on 20 years stored As10Se90 glass is studied using high-resolution X-ray photoelectron spectroscopy (XPS) technique. It is shown that high-energy irradiation treatment stimulates studied chalcogenide glasses (ChG) towards a more thermodynamically equilibrium state which cannot be attained when making glass by the conventional melt-quenching method.
