Arsenic triselenide is an inorganic chemical compound with the chemical formula Template:Chem2.
Amorphous arsenic triselenide is used as a chalcogenide glass for infrared optics. When purified, it transmits light with wavelengths between ca. 0.7 and 19 μm.[1]
In arsenic triselenide, arsenic is covalently bonded to selenium, where arsenic has a formal oxidation state of +3, and selenium −2.
Solution processed thin film Template:Chem2
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 Template:Chem2 glass films can be deposited from spin coating method from ethylenediamine solutions.[2]
