Barium selenide is an inorganic compound, with the chemical formula of BaSe. It is a white solid although typically samples are colored owing to the effects of air oxidation. [3]
BaSe has the lowest energy band gap among alkaline earth chalcogenides. [4]
Barium selenide can be obtained by the reduction of barium selenate in hydrogen flow:. [3] [5]
It can also be obtained by reacting selenium with barium carbonate or barium oxide at high temperature:[ citation needed]
Barium can also forms a series of polyselenide compounds, such as Ba2Se3, BaSe2 and BaSe3. [1]
