摘要: Laser-supported, dipole-assisted self-assembly results in blue-light guiding nanostructures, namely single-crystalline nanofibers of hexaphenyl molecules. The are up to 1 mm long, extremely well-aligned each other and their cross sections can be tuned span the range from nonguiding single optical modes at λ=425.5 nm. An analytical theory for such organic waveguides reproduce quantitatively experimentally observed behavior. From measured damping propagating, vibrationally dressed excitons imaginary part dielectric function isolated nanoscaled aggregates is determined.
