A method for manufacturing isotope-doped carbon nanotubes (10) includes the steps of: (a) providing a carbon rod (209) connected with an anode (214) of an electrical source, the carbon rod including at least two kinds of carbon isotope segments (202, 203) arranged therealong according to need; (b) providing a pure carbon rod (208) connected with a cathode (215) of the electrical source, the pure carbon rod positioned corresponding to the carbon rod and including carbon-12 isotopes; and (c) producing an arc discharge between the carbon rod and the pure carbon rod, wherein the carbon isotope segments of the carbon rod are consumed sequentially to form the isotope-doped carbon nanotubes on a surface of the pure carbon rod. Growth mechanisms of the isotope-doped carbon nanotubes manufactured by this method can be readily studied.
