Abstract:
A serious of tellurium based chalcogenide glass were prepared and investigated. As it being transparent nearly up to 25 μm and strong anti-hydrability, it becomes an optimized material for far-infrared application. Here, AgI was incorporated into the glasses acting as a glass modifier. With the help of AgI, a highest glass transition temperature, T(g) (151 °C) can be obtained. Detailed physics and chemic properties of the glasses were analyzed with DTA and XRD. The infrared optical transmission spectra were studied with the help of FTIR and Raman test. A purifying process was adopted to eliminate the affections of impurities in the tellurium glass. These serious of glasses are all high transparent in the 8-20 μm region, which fits for the applications of far-infrared optic imaging and sensing.
