    摘要: A method of separating, concentrating or purifying uniform carbon nanotubes with desired properties (diameter, chiral vector, etc) in a highly sensitive manner by the use of structure-sensitive properties peculiar to carbon nanotubes; and an apparatus therefor. There is provided a method of separating, concentrating, or purifying carbon nanotubes with the desired properties contained in a sample, comprising the steps of (a) irradiating a sample containing carbon nanotubes with light; and (b) selecting carbon nanotubes with desired properties. In a preferred embodiment, the light irradiation of the step (a) can be carried out in the presence of a metal so as to cause specified carbon nanotubes to selectively induce a photocatalytic reaction, resulting in metal deposition. Further, in a preferred embodiment, a given magnetic filed can be applied in the steps (b) so as to attain accumulation or concentration or carbon nanotubes with metal deposited.

    摘要: A process for producing a tape-like material uniformly containing highly pure single-walled or multi-walled carbon nanotubes and a tape-like material produced thereby; a high-performance field emission electrode including the tape-like material; and a process for producing the field emission electrode. The carbon nanotubes are synthesized by arc discharge, wherein an inert gas or inert gas-containing mixed gas is jetted onto a cathode having a carbon material from the inside of a hollow electrode (11) used as an anode, and simultaneously an arc is generated to form a path of arc discharge along a stream of the gas. At the same time, by relative movement of the electrodes, the cathode spot of the arc is moved on the cathode, and the synthesized carbon nanotubes are formed into a tape.
