Luminescent properties of Eu(TTA)(3)center dot 2H(2)O Complex (TTA: trifluorothenoyl-acetone) and Eu(DBM)(3)center dot 2H(2)O complex (DBM: dibenzoylmethane) in MMA (methyl methacrylate) solution had been studied in the presence of Ag colloidal nanoparticles. Luminescence of Eu (TTA)(3)center dot 2H(2)O complex was enhanced comparing to the Eu complex with the same concentration because it could aggregate around surface of Ag nanoparticles. Contrarily, luminescence of Eu(DBM)(3)center dot 2H(2)O complex was quenched with increasing in Ag colloidal concentration. The results are attributed to different structures between TTA and DBM.
