Abstract
The bi-layered coaxial hybrid nanostructures of polymer and inorganic metal nanotubes, such as light-emitting polythiophene (PTh), have been fabricated by a sequential electrochemical synthetic method based upon Al2O 3 nanoporous templates. The surface morphology of the nanostructures can be visualized by using SEM, TEM, and HR-TEM experiments. The bi-layered coaxial hybrid nanostructures of the PTh nanotubes coated with Cu are confirmed by the SEM and TEM images. The huge enhancement of photoluminescence (PL) of φ-conjugated PTh nanotubes coated with nanometer-scale metals has been observed, and can be accounted for by the effect of surface plasmon resonance. The surface-plasmon-enhanced PL of the polymers and inorganic metal hybrid nanotubes can be significantly applied to organic-based displays and nanometer-scale optoelectronics.
