Optical and thermo-mechanical properties of new Ge-Ga-Se-AgI glasses
Résumé
In this paper, the introduction of silver by incorporation of Agl in the family of chalcogenide glasses transparent from the visible range to 16 μm has been reported. A large glass forming region belonging to the GeSe2-Ga2Se3-Agl and able to accept more than 50 mol. % of Agl was discovered. Pure glasses, slightly transparent in the visible range up to 16 μm have been synthesized. A systematic study of thermo-mechanical and optical properties was performed. The possibility of shaping and drawing these glasses give them a great interest in ion exchange experiments to achieve gradient of the refractive index.
