Polarized fluorescent emission from aligned electrospun nanofiber sheets containing semiconductor nanorods

We fabricated sheets consisting of aligned electrospun polymer nanofibers embedded with semiconductor nanorods (NRs) and confirmed the production of polarized fluorescence emission. Electrospun nanofibers with embedded semiconductor NRs were rolled around a drum to form a sheet in which each nanofiber was aligned parallel to the rotation direction. The thickness and polarization ratio of the sheet were 1.5 μm and 0.6, respectively. We also examined how electrospinning parameters affected the polarization ratio of the sheet.
