Abstract
A series of Ge–Te–CuI far infrared transmitting chalcohalide glasses were prepared by traditional melt-quenching method and the glass-forming region was determined. Properties measurements include density, DTA, XRD, SEM, Vis–NIR and infrared (IR) transmission spectra. The results show that with the addition of CuI, the glass-forming ability is improved and nearly 30 mol% CuI can be dissolved into the Ge20Te80−x(CuI)x glass system. The density and glass transition temperature of Ge–Te–CuI chalcohalide glasses are within the range 5.459–5.960 g cm−3 and 150–184 °C, respectively. These glasses all have wide optical transmission window from 1.8 to 25 μm and offer an alternative solution for far infrared transmitting materials.
