Europium (Eu): Uses, Supply and Investment Guide
Europium is a rare earth element known for its red and blue luminescence, used in phosphors and in security features on banknotes. Europium demand fell sharply as LEDs replaced fluorescent lamps and older display technologies.

Europium Price
Europium prices fell after demand from fluorescent lighting collapsed. USGS reports an annual average for europium oxide.
For the rare earths that do have public price series, see the rare earth price charts, and how rare earth pricing works for why most rare earths have no transparent benchmark.
What Is Europium Used For?
- Phosphors. Europium-doped phosphors produce red and blue light in fluorescent lamps, some LEDs and older displays.
- Anti-counterfeiting. Europium compounds glow under ultraviolet light and are used in security features on euro banknotes.
- Nuclear control. Europium absorbs neutrons and has been used in reactor control rods.
Where Does Europium Come From?
Europium is present in small concentrations in most rare earth ores and is separated mainly in China. Europium sits on the boundary between light and heavy rare earths, and classification varies between sources.
China export controls on europium
China announced export controls on this element in October 2025, together with holmium, erbium, thulium, europium and ytterbium, then suspended them. The suspension runs to at least 10 November 2026; the US says it has been extended to 10 January 2027, but China has not published matching text.
How to Invest in Europium
Europium is a minor by-product for rare earth producers and is not a reason to invest in any company on its own.
For broader rare earth exposure, see the rare earth stock watchlist or the rare earth ETF comparison.
Europium Investment Risks
- Demand has been shrinking as LEDs replaced fluorescent lighting.
- Supply depends on Chinese separation and on the status of suspended export controls.
Europium FAQ
What is europium used for?
Europium is used mainly in phosphors that produce red and blue light and in anti-counterfeiting features on banknotes, including euro notes.
Why did europium demand fall?
Europium demand fell because LED lighting replaced fluorescent lamps, which used large amounts of europium-based phosphors.
Is europium a heavy or light rare earth?
Europium sits on the border between light and heavy rare earths. Some classifications group it with the heavy rare earths, others with the light ones.
