Abstract: Aligned nanotubes of organic electroluminescent material(NPB) were prepared by a simple melting method with an anodic aluminum oxide(AAO) membrane as the template. The nanotubes arrays obtained were characterized by means of scanning electron microscope(SEM), energy dispersive X-ray(EDX) analyzer, transmission electron microscope(TEM) and fluorescence microscope, respectively. The prepared nanotubes possessed a uniform shape and regular size. Further investigation indicated that the surface modification of the templates played an important role in the process of preparation. It was also worth mentioning that the nanotubes with different sizes exhibited a very interesting size-dependent photo-luminescence(PL) behavior.

Key words: N,N-Bis(α-naphthylphenyl)-4,4'-biphenyldiamine(NPB), Nanotube, Porous anodic aluminum oxide(AAO) template, Size-dependence of photo-luminescence(PL)
