Europium(II) fluoride is an inorganic compound with a chemical formula EuF2.

[1] Europium(II) fluoride can be produced by reducing europium(III) fluoride with metallic europium or hydrogen gas.

[3] Europium(II) fluoride is a bright yellowish solid with a fluorite structure.

[3] EuF2 can be used to dope a trivalent rare-earth fluoride, such as LaF3, 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.
