Two series of bis-beta-diketonate Eu3+ complex/polymer hybrid fibers, namely, Eu-2(BTP)(3)(H2O)(4)/PMMA (Eu/PMMA) and Eu-2(BTP)(3)(H2O)(4)/PVP (Eu/PVP) have been prepared by electrospinning technology (BTP = 1,3-bis(4,4,4-trifluoro-1,3-dioxobutyl)phenyl, PVP = poly (vinyl pyrrolidone) and PMMA = poly (methyl methacrylate)). The effect of complex u(2)(BTP)(3)(H2O)(4) on the luminescence, thermal stability and morphology of composite fibers were studied by characterization techniques. The Judd-Ofelt theory was applied to this study for explaining the effect of the distribution of Eu-2(BTP)(3)(H2O)(4) and the mutual effect of the u(2)(BTP)(3)(H2O)(4) coordination compound and neighboring chain segments of PMMA and PVP polymer matrix.
