The Europium(III) ternary complexes Eu(BID)3(PHEN) and Eu(MBID)3(PHEN) (BID – 2-benzoyl-1,3-indandione, MBID - 2-(4-methylbenzoyl)-1,3-indandione and PHEN – 1,10- Phenantroline) were synthesized, characterized and incorporated into poly methyl methacrylate (PMMA) and poly-N-vinylcarbazole (PVK) matrices. Emission properties in solid-state and polymer films were investigated through excitation spectra, emission spectra and absolute photoluminescence quantum yields (PLQY). Both complexes in their solid-state and films exhibited red-light luminescence with narrow bands corresponding to Eu(III) ion emission. In solid-state complexes were characterized with PLQY of 6% and 10%, in PVK matrices quantum yield dropped down to 4%, however, in PMMA films exhibited similar PLQY as in solid-state.
