Abstract

In this paper we report a method for tuning the distribution of SWCNTs produced by the anodic arc production method via the application of non-uniform magnetic fields to the gap region during synthesis. Raman, UV-visible near-infrared absorbance and near-infrared fluorescence spectroscopies were used to characterize samples together with SEM microscopy. Application of the non-uniform magnetic field (0.2 to 2) kGauss results in a broadening of the diameter range of SWCNTs produced towards decreased diameters, with substantial fractions of produced SWCNTs being of small diameter, less than  1.3 nm, at the highest field. The ability to tune production of the arc production method may allow for improvement in achievable SWCNT properties.
