Europium acetylacetonate is acoordination complex with formula Eu(C5H7O2)3. Although this anhydrousacetylacetonate 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 theEu3+ core gives the complex an unusualcharge-transfer band absent in other lanthanide acetylacetonates.[6] Thephotoluminescent emission lines occur near 465 (blue), 525 (green), and 579 nm (yellow), and are unusually sharp, especially the yellow doublet.[7] Doping a blend ofpolyacrylate andpolycarbonate with europium acetylacetonate enhances photoluminescence over a broad range ofultraviolet wavelengths.[8]EuFOD is a substituted derivative.
