Arsenic triselenide ( As 2 Se) is an 3 inorganic chemical compound, a selenide of arsenic.
Amorphous arsenic triselenide is used as a chalcogenide glass for infrared optics, as it transmits light with wavelengths between 870 nm and 17.2 µm.
Arsenic triselenide is covalently bonded. Even so, the arsenic has a formal
oxidation state of +3.
Solution processed thin film As 2Se 3 [2 ] [ edit ]
Thin film selenide glasses have emerged as an important material for integrated photonics due to its high refractive index, mid-IR transparency and high non-linear optical indices. High-quality As
2Se 3 glass films can be deposited from spin coating method from ethylenediamine solutions.
Arsenic triselenide should be kept away from strong bases in contact with aluminium or zinc and strong acids.
