The luminescence behavior of the dibenzoyl methane europium(III) complexes (Eu(DBM)(3)) in sol-gel derived host materials have been investigated. The steady-state excitation and emission spectra and the time-resolved spectra of the 1% EUCl3 and 3% DBM co-doped gel indicated an efficient ligand-to-metal energy transfer. The Eu(DBM)3 complexes in the gel showed longer 5 Do lifetimes in comparison with Eu(DBM)(3)(.)3H(2)O complexes. The luminescence intensity of the 1% EuCl3 and 3% DBM co-doped gel decreased continuously with increasing temperature and time of heat treatment, which indicated the gradual decomposition of the Eu(DBM)3 complexes in the gel during heat treatment.
