Europium Applications

Due to its ability to absorb neutrons, europium metal is used in nuclear reactors: neutron capturing cross section = 4500 barn. Europium oxide (Eu₂O₃) is used in water thermochemical decomposition in hydrogen power industry. Europium ions are used in visible light (orange colour, 610 nm) spectrum generation in solid state and liquid lasers.

Europium is a dopant in samarium monosulphide (thermogeherators) and as a doping component in super hard diamod-lile carbon nitride. Europium silicide is used as phosphor in microelectronics.

Europium cations are used in medicine as fluorescent probes. Radioactive isotopes are used in radiotherapy.
