Abstract

A chalcogenide base-glass of the Ge-Se-Te system was nucleated by various amounts (0.1- 0.50 mol%) of either ZrSe₂ or ZrTe₂. The aim of this study was to produce chalcogenide glass-ceramic materials with extended transmission in the infrared, up to 15 micrometers . The thermal, structural, and optical properties of such materials were investigated using DSC, SEM, EDAX, and FT-IR techniques. It was found that even small amounts of impurities, such as oxygen, cause uncontrolled nucleation and crystallization. The measurements revealed that in such cases, the crystalline particles formed in 'as quenched' glasses were those of the oxidized raw materials: SeO₂; GeO₂; or ZrO₂, and the transmission was greatly reduced even without further heat-treatment. In case of glasses prepared from purified starting materials, the nuclei formed were too small to be detected by x-ray analysis. The crystals formed after heat-treatment were GeSe₂ or GeTe₂. No apparent difference was found in the effect of either ZrSe₂ or ZrTe₂ on the thermal and optical properties of the prepared materials.
