Description

 

Cadmium sulfide is an inorganic compound. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite, but is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium. As a compound that is easy to isolate and purify, it is the principal source of cadmium for all commercial applications. It is mainly used as a pigment. Cadmium sulfide and cadmium selenide are used in manufacturing of photoresistors sensitive to visible and near infrared light. In thin-film form, cadmium sulfide can be combined with other layers for use in certain types of solar cells. It was also one of the first semiconductor materials to be used for thin-film transistors (TFTs). However interest in compound semiconductors for TFTs largely waned after the emergence of amorphous silicon technology in the late 1970s. It is also used as chemical raw material for glass and ceramic industry.
