  Abstract The luminescence of solid samples of europium mixed complexes with β-diketonates and o -phenanthroline (Phen), EuL 3 Phen, is investigated at 77 K in order to probe the structure of these compounds. A ligand-to-metal energy transfer process is evidenced. The quantum yields of 10 −5 M solutions in CH 2 Cl 2 are measured relative to 9,10-dichloroanthracene. Except for benzylacetonate, these
