Anwendungen

Zinc selenide (ZnSe) is used as an infrared optical material with wide transmission wavelength range. It is also used as an entrance optic in the new range of "in-ear" clinical thermometers. ZnSe is used as a semiconductor material for thin film devices, and n-type windows layer for thin film heterojunction solar cells. ZnSe activated with tellurium is a scintillator suitable for matching with photodiodes. It is used in x-ray and gamma ray detectors. Zinc selenide films are useful in photovoltaic cells and solar conversion cells. The material can be doped with n-type and p-type doping. It is used to form light-emitting diodes and diode lasers. ZnSe doped with chromium finds use as an IR laser gain medium.

Bemerkungen

Zinc selenide is chemically inert, non-hygroscopic and theoretically dense. It reacts with acids liberating toxic hydrogen selenide gas.
