• The mechanism of enhancement of emission quantum yield of the methanol solution of tris(dibenzoylmethano) europium (III) by triethylamine has been investigated. Lifetime of Eu<SUP>3+</SUP> resonance emission of the chelate did not change remarkably when triethylamine was added. The aspect of temperature dependence of the emission intensity was similar for both the chelate itself and the chelate-amine adduct under direct excitation of the metal level, but differed under excitation of the ligand. It was suggested that the sensitization is mainly due to a suppression of nonradiative process in the ligand triplet state.
