The Preparation of PVP/Tb(AA)3phen Luminescent Nanofibers by Electrospinning

Composite nanofiber films of poly(vinyl pyrrolidone) (PVP) containing Tb(AA)3phen were prepared by electrospinning technique. Transmission electron microscopy (TEM) and luminescence spectroscopy were used to characterize the composite nanofiber films. TEMobservation showed that Tb(AA)3phenwas dispersed homogeneously in composite nanofibers. Luminescence measurements indicated that Tb(AA)3phen showed superior emission lines and stronger intensities in the composite nanofibers than in pure Tb(AA)3phen powder. The lifetime of Tb(AA)3phen also lengthened when it was incorporated in the composite nanofibers.
