摘要：
In order to enhance the physicochemical properties and processability of rare earth complexes, and to further expand the practical applications in the field of anti-counterfeiting, fluorescent labeling and OLED, in this paper, novel luminescent composite fibers were prepared by electrospinning of PAN solutions containing the europium complex Eu(BPA)3phen. The characterization of the luminescent fibers has been investigated by scanning electron microscopy(SEM), energy dispersive spectroscopy(EDS), Fourier infrared spectrometer(FTIR), thermogravimetric analysis(TG-DSC) and fluorescence spectroscopy(PL). The results show that the diameter of composite fibers distributs between 200 nm to 400 nm, and random orientation. Thermogravimetric analysis indicates that the initial decomposition temperature of Eu(BPA)3phen/PAN composite fibers is 330℃, approximately. Furthermore, fluorescence spectra studies revealed that with the increasing of the incorporation of complexes into PAN, the fluorescence intensities were remarkable enhanced and reached its maximum value at 2.5% for Eu(BPA)3phen/PAN fibers. The further intensity decreased with the increasing content of the complexes because of typical emission concentration quenching. The novel luminescent composite nanofibers have potential applications in the field of anti-counterfeiting and OLED. © 2019, Science Press. All right reserved.
