Europium acetylacetonate is a compound with formula Eu(C₅H₇O₂)₃(H₂O)₂. It is a europium(III) complex with three acetylacetonate and two aquo ligands.^[2] The electronic structure of the Eu³⁺
core gives the complex an unusual charge-transfer band absent in other lanthanide acetylacetonates.^[3] The photoluminescent emission lines occur near 465 (blue), 525 (green), and 579 nm (yellow), and are unusually sharp, especially the yellow doublet.^[4] Doping a blend of polyacrylate and polycarbonate with europium acetylacetonate enhances photoluminescence over a broad range of ultraviolet wavelengths.^[5] EuFOD is a substituted derivative.
