Zinc 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.

YELLOW SHINY FINE POWDER

ZnSe is insoluble in water, but reacts with acids to form toxic hydrogen selenide gas. It can be deposited as a thin film by chemical vapour deposition techniques including MOVPE and vacuum evaporation.

Fire risk in contact with water or acids.

Zinc Selenide is produced by synthesis from Zinc vapour and H2Se gas, forming as sheets on Graphite susceptors. Another method of producing is a growth from melt under excessive pressure of inert gas (Ar usually).
