Bead-on-string fibers electrospun from terbium acetylacetonate hydrate doped poly methyl methacrylate

Bead-on-string fibers have been electrospun from terbium acetylacetonate hydrate (TAH) doped PMMA. The beads with a size of about 5μm and fibers with diameters about 300-600 nm are confirmed to form cross-links by SEM, which is helpful to the stability of silk-particle coexistence network. Under ult...

description	Bead-on-string fibers have been electrospun from terbium acetylacetonate hydrate (TAH) doped PMMA. The beads with a size of about 5μm and fibers with diameters about 300-600 nm are confirmed to form cross-links by SEM, which is helpful to the stability of silk-particle coexistence network. Under ultraviolet (UV) radiation, luminescence comparison between TAH/PMMA bulks and bead-on-string fibers with fluorescence enhancement in the latter verifies the effectiveness of electrospun. Further, when the beads and fibers reach the proper range, the greatest improvement of intensity is obtained. The greatest emission powers and the emission photon numbers of TAH/PMMA bead-on-string fibers in visible region are identified to be 32.07μW and 8.8 × 1013cps, respectively, which are nearly four times higher than those of the TAH/PMMA bulks under the 308nm UVB-LED pumping, and the highest luminous efficacy is up to 13.94%. Improved fluorescence behavior and conclusive photon quantification demonstrate the potential of TAH/PMMA bead-on-string fibers as UV-visible conversion layer of flexible solar cells applying in wearable electronic devices.
