  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.

    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.

    en.wikipedia.org/.../List_of_semiconductor_materials

    A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).

    en.wikipedia.org/wiki/Selenium_compounds

    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.

    Commercially significant is zinc selenide, which is used in some infrared optics. Cadmium selenide is a pigment but its use has been declining because of environmental considerations. Copper indium selenide (CuInSe 2) has attractive potential for photovoltaic devices, but these applications have not been implemented widely. [1]

    A Walmart spokesperson told Fortune that any price changes are speculative at this point, but future tariff-induced cost increases would be an additional burden to already price-sensitive shoppers.

  9. 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).
