Europium compounds

Europium compounds fluoresce under UV light at 395 nm and 365 nm.[1]

Europium compounds are compounds formed by the lanthanide metal europium (Eu). In these compounds, europium generally exhibits the +3 oxidation state, such as EuCl3, Eu(NO3)3 and Eu(CH3COO)3. Compounds with europium in the +2 oxidation state are also known. The +2 ion of europium is the most stable divalent ion of lanthanide metals in aqueous solution.[2] Many europium compounds fluoresce under ultraviolet light due to the excitation of electrons to higher energy levels.[1] Lipophilic europium complexes often feature acetylacetonate-like ligands, e.g., Eufod.
