Europium(II) fluoride is an inorganic compound with a chemical formula EuF<sub>2</sub>. It was first synthesized in 1937.
Europium(II) fluoride can be produced by reducing europium(III) fluoride with metallic europium or hydrogen gas.
Europium(II) fluoride is a bright yellowish solid with a fluorite structure.
EuF<sub>2</sub> can be used to dope a trivalent rare-earth fluoride, such as LaF<sub>3</sub>, to create a vacancy-filled structure with increased conductivity over a pure crystal. Such a crystal can be used as a fluoride-specific semipermeable membrane in a fluoride selective electrode to detect trace quantities of fluoride.
