Zinc selenide is the inorganic compound with the formula ZnSe. It is a lemon-yellow solid although most samples have a duller color due to the effects of oxidation. It is an intrinsic semiconductor with a band gap of about 2.70 eV at 25 °C (77 °F), equivalent to a wavelength of 459 nm.
“Zinc oxide can help soothe skin irritation and inflammation, ... In fact, it’s safe for people with rosacea, acne, or other skin conditions, says Dr. Rodney, as the ingredient “helps soothe ...
Stilleite is a selenide mineral, zinc selenide, with the formula Zn Se.It has been found only as microscopic gray crystals occurring as inclusions in linnaeite associated with other selenide and sulfides.
The selenide dianion Se 2− forms a variety of compounds, including the minerals from which selenium is obtained commercially. Illustrative selenides include mercury selenide (HgSe), lead selenide (PbSe), zinc selenide (ZnSe), and copper indium gallium diselenide (Cu(Ga,In)Se 2). These materials are semiconductors.
Typical materials for ATR crystals include germanium, KRS-5 and zinc selenide, while silicon is ideal for use in the Far-IR region of the electromagnetic spectrum. The excellent mechanical properties of diamond make it an ideal material for ATR, particularly when studying very hard solids, although the broad diamond phonon band between 2600 and ...
Compared to the more common zinc selenide-based optics, materials such as thallium bromoiodide enable transmission at longer wavelengths. In the infrared , this allows for measurements as low as 350 cm −1 (28 μm), whereas zinc selenide is opaque by 21.5 μm, and ZnSe optics are generally only usable to 650 cm −1 (15 μm).
Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...
ZnSe has a reasonably large Verdet constant (roughly 1 min. cm-1 G-1 at = nm) and was suggested for use in optical isolators, see Wunderlich J. A. and DeShazer L. G., Applied Optics 16 (6), 1584 (1977). Note that although the rare-earth orthoferrites have much higher Verdet constants, they are birefringent and aren't much good at producing ...
