Chalcogenide
A chalcogenide is a chemical compound consisting of at least one chalcogen ion and at least one more electropositive element. Although all group 16 elements of the periodic table are defined as chalcogens, the term is more commonly reserved for sulfides, selenides, and tellurides, rather than oxides.
Photoconductive chalcogenide glasses are used in xerography and television.[citation needed]
An optical processing chip made from a chalcogenide has been developed by The University of Sydney with potential to speed up links between optical fibre networks and computers.[1]
