  Abstract: The luminescence of solid samples of   europium mixed complexes with beta-diketonates and   o-phenanthroline (Phen), EuL3Phen, 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 CH2Cl2 are measured relative to   9,10-dichloroanthracene. Except for benzylacetonate, these yields   are quite low, due to the presence of low-lying electronic states   of the ligands. The crystal structure of Eu(NO3)(DBM)2(TBPO)2 as   well as its photophysical properties in CH2Cl2 solution are   presented
