Europium acetylacetonate is a coordination complex with formula Eu(C5H7O2)3. Although this anhydrous acetylacetonate complex is widely discussed,[2] some sources suggest that it is really the dihydrate Eu(C5H7O2)3(H2O)2.[3][4]
The electronic structure of the Eu3+ core gives the complex an unusual charge-transfer band absent in other lanthanide acetylacetonates.[6] The photoluminescent emission lines occur near 465 (blue), 525 (green), and 579 nm (yellow), and are unusually sharp, especially the yellow doublet.[7] Doping a blend of polyacrylate and polycarbonate with europium acetylacetonate enhances photoluminescence over a broad range of ultraviolet wavelengths.[8]EuFOD is a substituted derivative.
