英文摘要
In metallic carbon nanotubes, we have succeeded to observe photoluminescence due to excitons with the lifetime of 40 fs. From femtosecond luminescence spectroscopy, the formation and relaxation times of trions in hole-doped semiconducting nanotubes are found to be 80 fs and 380 fs, respectively. In semiconducting carbon naotubes encapsulating metallofullerenes, a carrier doping effect from metallofullerenes to nanotubes is observed, and third-order nonlinear optical responses are investigated. We have also investigated exciton energy transfer between nanotubes in the femtosecond time region.
