Paper Abstract

Specially designed surface micro- and nanostructures allow one to steer the bottom up self-organized growth of crystalline nanoaggregates from wide bandgap organic molecules, which possess extraordinary optoelectronic properties. Polarized light-emitting para-hexaphenylene nanofiber arrays exemplify such "self-growing" nanophotonic devices. The methodology behind this growth is an alternative to transfer of nanofiber arrays from specific growth substrates onto device platforms. We compared the optical properties of transferred and in situ grown nanofibers in terms of polarization function and emission homogeneity and also studied the temperature dependence of the emission spectra of transferred nanofiber arrays. Both types of nanofibers show the same spatial emission characteristics along their long axes and also the same polarization ratio. However, in nanofiber arrays, the polarization ratio decreases in the case of structured surface-grown nanofibers since the mutual orientation of the nanofibers is less perfect than for transferred fibers.
