Wavelength-resolved femtosecond transient absorption spectroscopy is used to follow the electronic dynamics of single-walled carbon nanotubes in polymers following visible photoexcitation. Electron-hole (e-h) pairs features give rise to sharp features in the transient spectra that decay in amplitude and exhibit rapid spectral shifts. The decay reflects (e-h) recombination oil both short (1.3 ps) and long (35 ps) time scales. Transient Spectra also exhibit a broad photobleach at early times that arises front the cooling of a hot electron gas created via excitation at the red edge of a pi-plasmon hand.
