Application / Uses Preparation Cadmium selenide is a semiconducting material, but has yet to find many applications in manufacturing. This material is transparent to infra-red (IR) light, and has seen limited use in windows for instruments utilizing IR light.
Application / Uses Preparation Lead selenide is a semiconductor material. It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. (Note that incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) It is a grey crystalline solid material.
Application / Uses Preparation Sodium selenide is a inorganic compound of sodium and selenium with the chemical formula Na2Se. This colourless solid is prepared by the reaction of selenium with a solution of sodium in ammonia
Application / Uses Preparation A selenide is a chemical compound in which selenium serves as an anion with oxidation number of −2 (Se2−), much as sulfur does in a sulfide. The chemistry of the selenides parallels that of the sulfides
Application / Uses Preparation Zinc selenide (ZnSe), is a light yellow binary solid compound. It is an intrinsic semiconductor with a band gap of about 2.70 eV at 25 °C. ZnSe rarely occurs in nature. It is found in the mineral stilleite named after Hans Stille.
