Metal chalcogenide

Metal chalcogenide

In chemistry, metal chalcogenides are compounds consisting of a metal and an element which is a member of the chalcogen column of the periodic table. While oxygen is a member of the chalcogens, so all metal oxides are technically metal chalcogenides, the term is commonly used only to refer to compounds of a metal with sulfur, selenium or tellurium, and polonium.

Important metal chalcogenides include the semiconductor cadmium sulfide, which is used in the production of photoresistors, and cadmium selenide, which is used to produce quantum dots.
