Europium metal is now known to be highly reactive; the element's most stable oxidation state is +3, but the +2 state also occurs in solid-state compounds and water.

A Swiss innovation could open an exciting new chapter for recycling fluorescent lamps. Researchers at the Institute of ...

This clay matrix is used to stabilize and enhance the performance of two key components: europium(III) (or Eu(III)) complexes, which provide vibrant luminescence, and heptyl viologen (HV 2 ...

Found at the very bottom of the periodic table, rare earth elements, such as europium, have shown promise for use in quantum information devices due to their unique atomic structures. Specifically ...

The device simultaneously controls color and light emission at low voltage by embedding color-changing viologen derivatives and luminescent europium(III) complexes in a layered clay matrix.
