Metal chalcogenides are compounds composed of a metal and a member of the chalcogens, which include the elements oxygen, sulfur, selenium, tellurium, and polonium. The term chalcogenide is typically only used to refer to sulfur, selenium, and tellurium, however. Metal chalcogenides of importance include the semiconductor cadmium sulfide, which is used in the production of photoresistors, and cadmium selenide, which is used to produce quantum dots.
