Chemistry & industry
Applications
DescriptionZinc selenide (ZnSe) is an II-VI compound semiconductor material with a face-centred cubic crystal structure and excellent physicochemical properties, which has a wide range of transmittance, from 0.5 microns to 19 microns. Zinc selenide is a very good infrared material, mainly used in infrared optics and optoelectronics, and can be used to manufacture window materials, focusing lenses, beam splitters, prisms, and CO2 lasers. Zinc selenide is also commonly used as lenses and windows for CO2 lasers due to its good imaging and thermal shock properties.
UsesZinc 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.
