A facile nanotemplate preparation method for [60]fullerene nanofibres: surface-wetting

Abstract

Highly-ordered and well-aligned fullerene nanofibre arrays were fabricated via a nanotemplate preparation method and surface-wetting technique. The as-prepared fullerene nanofibre arrays were characterized by field-emission scanning electron microscopy, transmission electron microscopy, ultraviolet-visible absorption spectra and X-ray diffraction analysis. The dual-layered photoreceptors containing the fullerene nanofibre arrays or bulk fullerene films as the charge-generation layer (CGL) were fabricated. The photosensitivity of photoreceptors with fullerene nanoarrays as CGL was improved by one order of magnitude compared to that of their bulk films. The effect of the diameter and the length of the fullerene nanofibres on the photosensitivity of the photoreceptors was also investigated.
