Influence of the Resonant Electronic Transition on the Intensity of the Raman Radial Breathing Mode of Single Walled Carbon Nanotubes during Electrochemical Charging

Popis výsledku v původním jazyce

In situ Raman spectroelectrochemistry has been used to probe the E11S and E22S electronic transitions of the semiconducting single walled carbon nanotube tube (6,5). These two transitions were investigated through the intensities of the radial breathingmode by using 1.16 and 2.18 eV laser excitation energies, respectively. The bleaching behavior of the (6,5) tube is similar for both laser excitation energies if the magnitude of the applied electrode potential is smaller than about 0.5 V. At potentialsoutside the 0.5 V window, the intensity/ potential profile is steeper for the 1.16 eV laser excitation. But a significant bleaching of the Raman signal is observed also for the 2.18 eV laser excitation energy even at mild potentials. This behavior showsthat the filling of the E11S electronic state has a strong impact also on the E22S electronic transition.
