We present studies of the ultrafast carrier dynamics in single-walled carbon nanotubes using femtosecond fluorescence and transient absorption techniques. We find that the dynamics are dependent on excitation intensity and the electronic transitions initially excited
We present the utility of 2-D electronic spectroscopy for the investigation of energy transfer dynamics in photosynthetic light-harvesting systems. Elucidating ultrafast energy transfer within photosynthetic systems is difficult due to the large number of molecules and complex environments involved in the process. In many spectroscopic methods, these… (More)
Three-pulse photon echo peak shifts of single-walled carbon nanotubes were recorded at 975 nm, showing an initial value of 26 fs, a dominant decay time of 59 fs and an oscillatory frequency of 282 cm"'.
