Luminescent PAN Fibers Doped with Tb3+ by Electrospinning

In this study, monodispersed Tb3+ ions were successfully dispersed in the polyacrylonitrile (PAN) solution. Tb3+/PAN composite fibers were fabricated by electrospinning the PAN solutions containing different amount of Tb3+ ions. Further investigation showed that Tb3+ ions were homogeneously dispersed in the fibers individually. The composite fibers showed a uniform and continuous morphology. The as-spun fibers were characterized by Field Emission Scanning Electron Microscope (FE-SEM) and X-ray diffraction (XRD)
