Description
In situ optical emission spectroscopy(OES) was used to investigate the spatial and temporal evolution of the electron temperature(Te) of laser induced plasmas in the laser-furnace method of synthesizing single-walled carbon nanotubes (SWCNTs). The intensities of the spectral maps of Te showed a strong temperature dependence. The frequency of sharp fluctuations which appear as hot spots in the spectral maps of Te increased as the furnace temperature was increased from 1073 K to 1273 K.
