Structural, Thermal, and Fluorescence Properties of Eu(DBM)3Phenx Complex Doped in PMMA

摘要: Tris (dibenzoylmethanido) (o-phenanthroline)-europium(III) complexes [Eu(DBM)3(Phen)x] have been synthesized, and their structural, thermal, fluorescence properties investigated both as an independent complex also after embedding it in poly(methyl methacrylate) (PMMA) polymer matrix. X-ray analysis reveals unusual crystalline to amorphous transformation structure of the Eu(DBM)3Phenx when x exceeds 1.0 (mole %). Differential scanning calorimetry (DSC) Fourier transform infrared spectroscopy (FTIR) depict interaction between PMMA The intensity Eu3+ ion Eu(DBM)3Phen1·5 is order magnitude larger compared Eu(DBM)3·2H2O complex. In addition transition 5D0 → 7F2, which has a rise time 83 μs, transitions from 5D1 5D2 levels are observed, along with several ligand field splittings Appearance (∼0.76 ns) ...
