Copper(I) Selenide
Copper(I) selenide is an inorganic binary compound between copper and selenium, with the chemical formula Cu2Se. Properties Stoichiometric copper selenide is a zero-bandgap material with metal-like behavior. Copper-deficient Cu2−''x''Se (non-stoichiometric) is an intrinsic p-type semiconductor with direct and indirect bandgap energies in the range of 2.1–2.3 eV and 1.2–1.4 eV respectively. It is frequently grown as nanoparticles or other nanostructures. Uses Copper(I) selenide is produced in situ is a Latin phrase meaning 'in place' or 'on site', derived from ' ('in') and ' ( ablative of ''situs'', ). The term typically refers to the examination or occurrence of a process within its original context, without relocation. The term is use ... to form a protective black coating on iron or steel parts in some cold-bluing processes.

Copper(II) Selenide
Copper(II) selenide is an inorganic binary compound between copper and selenium, with the chemical formula CuSe. Uses Copper(II) selenide is produced in situ to form a protective black coating on iron or steel parts in some cold-bluing processes. Bluing solutions that operate in this manner will typically be labeled as containing selenous acid or selenium dioxide. It has also been investigated for use in the treatment of colon cancer. Natural occurrences Copper selenides are the most common selenium minerals. CuSe is known in mineralogy as klockmannite.

Selenides
A selenide is a chemical compound containing a selenium with oxidation number of −2. Similar to sulfide, selenides occur both as inorganic compounds and as organic derivatives, which are called organoselenium compound. Inorganic selenides The parent inorganic selenide is hydrogen selenide (H2Se). It is a colorless, malodorous, toxic gas. It dissolves in aqueous solution, to give the hydrogenselenide or biselenide ion HSe−. At higher pH, selenide forms. Solutions of hydrogen selenide and selenide are oxidized by air to give elemental selenium: : Most elements form selenides. They sometimes have salt-like properties, e.g. sodium selenide, but most exhibit covalent bonding, e.g. molybdenum diselenide. Their properties are diverse, mirroring the diverse properties of the corresponding sulfides. As indicated by the fact that only a few thousand tons of selenium are produced annually, the subset of selenium compounds called selenides find few applications. Commercially s ...
