2. Zinc selenide - Wikipedia

   en.wikipedia.org/wiki/Zinc_selenide

   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.

3. Selenium compounds - Wikipedia

   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.

4. Stilleite - Wikipedia

   en.wikipedia.org/wiki/Stilleite

   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.

5. Thallium halides - Wikipedia

   en.wikipedia.org/wiki/Thallium_halides

   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).

6. Zinc compounds - Wikipedia

   en.wikipedia.org/wiki/Zinc_compounds

   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 ...
