Abstract

© 2016 Wiley Periodicals, Inc. Solutions of poly(9-vinylcarbazole)/4,7-diphenyl-1,10-phenanthroline (PVK/Bphen) and poly(9-vinylcarbazole)/tris-(8-hydroxyquinoline) aluminum (PVK/Alq3) were individually delivered either to the inner or the outer needle of a coaxial spinneret for electrospinning to prepare green luminescent PVK/Bphen/Alq3 composite fibers. The influence of both flow rate and applied voltage on the photoluminescence of the composite fibers was evaluated. Scanning electron microscopy showed ribbon-like fibers with uneven surfaces and thickness of about 5 µm. Raman spectroscopy and fluorescence microscopy revealed that Bphen was homogenously dispersed in the PVK fibers; Alq3 was not. Photoluminescence shows strong evidence that there are marked conditions where emission of the co-electrospun PVK/Bphen/Alq3 fibers significantly improved as compared with those produced by simple electrospinning. It is suggested that the enhanced dispersion of the Alq3 allowed a more efficient energy transfer from the PVK to the Alq3. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44019.
