Abstract The relative photoluminescence yield for (1,10-phenanthroline)europium(III) tris-thenoyltrinuoroacetonate (Eu(tta)3Phen). an efficient enhancer of chemiluminescence, has been measured under the conditions (temperatures and solvents) specific for the oxidation of hydrocarbons. The yield is independent of viscosity and the presence of a heavy atom in the solvent, but the higher the polarity of the medium, the more the yield decreases as the temperature increases. The effect is interpreted as an acceleration of radiationless deactivation occurringvia the mechanism of electron transfer from a ligand to the excited Eu3+ ion.
