Dye-doped, submicron fiber waveguides composed of hole- and electron-transport materials, with a mean diameter of 480–660 nm were fabricated and their waveguiding properties studied. Dye emitted photoluminescence was guided in the fibers and the loss coefficient was calculated to be 1.2 × 10−3–3.9 × 10−3 μm−1 at a wavelength of 540 nm, which is lower than previously reported for optically active polymer...
We fabricate single electrospun polymer nanofibers consisting of poly(vinylcarbazole) (PVCz) doped with 4,4'-bis [(N-carbazole)styryl]biphenyl (BSB-Cz). The diameter of the fibers measured by scanning electron microscopy is approximately 300 nm. Waveguiding in a fiber is confirmed by comparing the photoluminescence intensities of the middle and end of a fiber. We confirm that the guided light is mainly...
