Europium(III) fluoride

Europium(III) fluoride is an inorganic compound with a chemical formula EuF3.

Production
Europium(III) fluoride can be produced by reacting europium(III) nitrate and ammonium fluoride:
 * Eu(NO3)3 + 3 NH4F → EuF3 + 3 NH4NO3

Europium(III) fluoride nanoparticles can be synthesized by microwave irradiation of europium(III) acetate in an ionic liquid that has tetrafluoroborate as the anion.
