Description

Cadmium sulfide is used as a pigment in the chemical industry; for manufacturing of photoresistors, optical-electronic pairs, photodiodes, solar batteries and phosphors. Single crystals of cadmium sulfide are used for the preparation of optical devices operating in the infrared regaion of spectrum. Cadmium sulfide is a direct band gap semiconductor with a band gap band from 2.42 to 2.57 eV.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
