Chalkogenide glasses are known for their high infrared transparency, and are Filter materials for infrared (IR) optical applications. However, they are also known Possess thermal and mechanical stability is low compared to oxide glasses. The The computations studied were (Ge20Se18Te62) 100-Zix (X = 0, 8). The samples were Prepared by refrigeration refrigeration technology. X-ray diffraction was performed in the 5-to-5 range 900. The samples were proved to be amorphous. Thermal properties and glass Temperature Switching GG, Start Crystallization, TEC peak crystallization was measured Using DSC at a constant constant heating rate equals 10 K / min. Also, measurements Electrical conductivity at constant current values to estimate the temperature An electric track was performed. I-V electrical curve measurements of the samples have It was achieved at a different ambient temperature. Also, electrical measurements Conductivity at constant current value to estimate the temperature of its electrical path It has been done. Infrared spectra that range from 400 to 4000 cm -1 were measured in the chamber The temperature for all glasses is prepared. Effect of both iodine content and heat The temperature is assessed on the optical properties. The electron microscope was microscope
