Fluorescence study of Eu chelates in solution and polymer matrix

The fluorescence spectra of Eu chelates with different neutral ligand in methyl methacryate (MMA) solution were measured and the influence of the neutral ligand was analyzed. The chelate Eu(DBM)3(TOPO)2, which shows the strongest fluorescence intensity in the solution, has been incorporated into the poly(methyl methacryate) (PMMA) matrix. According to the fluorescence emission spectrum, its radiative properties were also predicted.
