説明
<jats:title>Abstract</jats:title><jats:p>The temporal and spatial evolution of emitting carbon nanoparticles were investigated using a laser furnace apparatus combined with a high-speed video camera. An apparent increase in the blackbody emission intensity at Δt > 400 [.proportional]sec after laser vaporization of a graphite rod was clearly recognized. Also, it was found that this increasing tendency corresponds well to that of the fullerene yield, where fullerene species was obtained as sublimed carbon material using <jats:italic>in situ</jats:italic> sublimation method. These findings suggest that a certain exothermic process related to the formation of C<jats:sub>60</jats:sub>, other higher fullerenes, and carbon nanotubes should occur at Δt > 400 νsec inside the furnace.</jats:p>
