Large-Scale Production of Single-Walled Carbon Nanotubes using Ultrafast Pulses from an FEL

PDF Version Also Available for Download.

Description

We report very high production rates of SWNTs from carbon vapor produced by ultrafast ({approx}0.5 ps) pulsed infrared radiation from the Free Electron Laser (FEL) at Thomas Jefferson National Accelerator (Jlab). To harness the high average power ({approx} 1 kW average power) of this FEL beam, a new vaporization geometry was developed in which the laser radiation impinges on the sidewall of a translating and spinning, carbon rod. Using only 30% of the available FEL average power at a wavelength of {approx}3 microns, we have been able to generate carbon soots rich in bundles of SWNTs at the rate of ... continued below

Using only 30% of the available FEL average power at a wavelength of {approx}3 microns, we have been able to generate carbon soots rich in bundles of SWNTs at the rate of {approx}1.5 gm.h. Samples were characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), Temperature programmed oxidation (TPO), and Raman spectroscopy.
