摘要: Here, we report an innovative electrospun composite nanofiber having a complex of Eu(TTA)3Phen doped in matrix polymer blends prepared by electrospinning for designing smart fabrics. Europium contains 2-thenoyltrifluoroacetone(TTA), 1,10-phenanthroline(Phen) and europium. It was synthesized co-precipitation technique the preparation nanofibers Eu(TTA)3Phen/polymer such as Eu(TTA)3Phen/PVDF-PMMA(Polyvinylidene fluoride-Polymethylmethacrylate) Eu(TTA)3Phen/PVDF-PS(Polyvinylidene fluoride-Polystyrene. Nanofibers were characterized Scanning Electron Microscopy (SEM), Fourier Transform Infra Red (FTIR), X-ray diffraction (XRD) Photoluminescence (Pl). study shows red emission which is allocated to transitions between first excited state (5D0) multiplet states (7F0-4). Due integration into subsequent distortion symmetry around Eu3+ ions chapping Polymer, polarization improved, increased probability electronic dipole allowed transitions. The Judd-Ofelt theory used calculate intensity parameters from data Eu(TTA)3Phen/polymers blends. As compared PS PMMA, presence PVDF both generally increases hypersensitive transition perhaps responsible enhancement photoluminescence properties. Electrospun Eu(TTA)3Phen/PVDF-PS Eu(TTA)3Phen/PVDF-PMMA can be important candidate photoluminescent
