Abstract

In this paper, the introduction of silver by incorporation of AgI 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-AgI and able to accept more than 50 mol. % of AgI 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..
