The C60 moiety in the product was about 1. 2% (mass fraction). The photoconductlvity study revealed that the photoconductivity of PVK was improved obviously through grafting C60.The half time of light decaying (t1/2) of CGP reached 0. 35 s.展开更多

As the solvent evaporation, the nanotubes were formed. The morphology of the sample was examined by SEM and fluorescence of PVK and PVK-C60 was determined. Emis- sion intensity of PVK was weakened by C60, indicating that C60 improved the conductive property of PVK nan- otubes.展开更多
