摘要

The photoresponse and photoconductivity properties of micron-sized C60 whiskers and sub-millimeter-sized C60 clusters are successfully studied by the microfabrication technologies.According to the ultraviolet-visible-near infrared (UVVis-NIR) absorption spectroscopic study,a highly intense absorption is observed in the UV and visible light regions,which indicates probable applications in photoelectric devices.Furthermore,a large photoeurrent is measured under the illumination of white light in nitrogen (N2) atmosphere.The micron-sized C60 whiskers and the sub-millimeter-sized C60 clusters have different photoresponse curves under the same condition of measurement.A quick transformation of photoelectric response is detected in parallel multi-arranged micron-sized C60 whiskers,but the recovery of the photocurrent of self-assembly sub-millimeter-sized C60 clusters is much slower.
