Abstract

The effect of electron-irradiation on the optical and refractometric properties of As2S3 chalcogenide glasses is studied. Irradiation-induced optical pseudogap shrinkage as well as increase absorption edge energy width, refraction index and molar refraction are revealed. Additional absorption edge smearing is shown to result from the increase of contribution of static structural disordering into the absorption edge energy width, and the refractive index increase is caused by the increase of molar refraction (electron polarizability) due to the radiation-induced changes..
