Influence of NaX (X=I or Cl) additions on GeS2-Ga2S3 based glasses
Résumé
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 addn. on two different host glasses (GeS2)80(Ga2S3)20 and (GeS2)72(Ga2S3)28. Macroscopic properties including d. and characteristic temps., such as glass transition temps. Tg and crystn. temp. Tx, were detd. for a max. molar content of NaX equal to 15%. The evolution of the optical band-gap and the chem. stability following the compn. were also studied. Cond. 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 d.
