Abstract
We investigated luminescence decay kinetics in single-walled carbon nanotubes in large bundles excited by femtosecond pulses. The time constant of luminescence decay becomes longer with decrease in photon energy: 40Â fs at 1.2Â eV and 380Â fs at 0.6Â eV. This behavior is explained by exciton energy transfer from an excited to neighboring tubes.
