Influence of Polymer in Photoluminescence Properties of Electrospun Eu~(3+) Doped Polymer Nanofibers

摘要

Eu~(3+) doped polymer nanofibers were fabricated by electrospinning technique using various polymers such as poly(vinylidene fluoride) (PVDF), polyethylene oxide (PEO), poly(vinyl pyrrolidone) (PVP) to study the influence of polymer in their photoluminescence properties. As-fabricated nanofibers were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX) and photoluminescence (PL). Spectral analysis of Polymer/Eu~(3+) nanofibers was based on their emission spectra. The photoluminescence property shows superior bright red emission spectra from the Eu~(3+) and relatively stronger hypersensitive behavior of the ~5D_0→ ~7F_2 transition. Eu~(3+) doped polymeric nanofibers are very much suitable for photoluminescent fabric designing in smart textiles. The enhanced properties of this photoluminescence indicated a more polarized chemical environment for the Eu~(3+) ions and greater hypersensitivity for the ~5D_0 →~7F2 transition, which showed the potential for application in various polymer optoelectronic devices.
