WebAn example of this is gallium sulphide based glasses. Gallium sulphide on its own is not a known glass former however it readily bonds with sodium or lanthanum sulphides to form a glass, gallium lanthanum sulphide (GLS). Amorphous chalcogenide materials can be broadly classed by the type of atoms to which they bond to form amorphous systems. ... For both the practical application and scientific study of chalcogenide glasses, glass purity is of utmost importance. Varying levels of trace impurities, even at levels of a few parts per million can alter the spectroscopic behavior of a glass. Similarly, impurities are a major concern for optical components. Impurities in the raw materials and hence in the resulting glass, contribute to the loss of power through an optical component, whether it is in the form of a long glass fiber or an infrare…
