Telluride glasses with far-infrared transmission up to 35 μm

Abstract : Telluride glasses are very attractive due to their unique infrared transparency window compared to other chalcogenide glasses. The extension of their infrared transmission by changing the composition appears to be very challenging. Glasses in the (GeTe4)100-x(AgI)x system, with 5 ≤ x ≤ 30 have been synthesized using the melt-quenching method. The effect of the addition of silver iodide is a widening of the infrared transparency range up to 35 μm that is much larger than for any other chalcogenide glass families. Moreover, the moulding of these telluride glasses is also achievable without affecting the optical properties. © 2017
