INFO

Zinc selenide, ZnSe

Zinc selenide (ZnSe) is a binary compound semiconductor with a cubic zinc blende structure. This material is transparent in the visible and near-infrared regions of the electromagnetic spectrum, with a wide direct bandgap of approximately 2.7 eV. Due to its transparency and high refractive index, ZnSe has become a popular choice for high-power infrared laser systems, especially CO₂ lasers, where ZnSe optics are used as output couplers and beam expanders. ZnSe can also be doped with various elements, most notably with chromium (Cr:ZnSe), to produce mid-infrared solid-state lasers. In addition, ZnSe is utilized in the fabrication of light-emitting diodes, photodetectors, and solar cells.
