Effect of Te addition on some physical properties of the Se3S2 system and a study of the response to gamma-irradiation

摘要

Glasses based on sulphur and tellurium were carefully characterized to establish the interdependence between chemical composition and the magnitudes of the physical parameters related to their use as infrared optical materials. Parameters considered in this paper are density, molar volume, transition temperatures, crystallization activation energy, decomposition energy, direct current (d.c.) electrical properties, optical energy gap and infrared transmission spectra in the range 400-6000 cm(-1). The gamma irradiation has no detectable effect on both the d.c. conductivity of the bulk glass and the optical energy gap. (C) 1998 Kluwer Academic Publishers. [References: 21]
