摘要：

Chalcogenide glasses in the pseudo-ternary system NaX-GeS2-Ga2S3 (X=Cl or I) were synthesized. Different series were investigated in order to highlight the influence of the sodium halide addition on two different host glasses (GeS2)(80)(Ga2S3)(20) and (GeS2)(72)(Ga2S3)(28). Macroscopic properties including density and characteristic temperatures, such as glass transition temperatures T-g and crystallization temperature T-x, were determined for a maximum molar content of NaX equal to 15%. The evolution of the optical band-gap and the chemical stability following the composition were also studied. Conductivity measurements were also performed and compared to other Li-based GeS2-Ga2S3 glasses. The results were discussed taking into account the cation and anion nature and also the glass packing density. (C) 2014 Elsevier Inc. All rights reserved.
