Exponential decay lifetimes of excitons in individual single-walled carbon nanotubes.
The dynamics of excitons in individual semiconducting single-walled carbon nanotubes was studied using time-resolved photoluminescence (PL) spectroscopy. The PL decay from tubes of the same (n,m) type was found to be monoexponential, however, with lifetimes varying between less than 20 and 200 ps from tube to tube. Competition of nonradiative decay of excitons is facilitated by a thermally acti...
متن کاملNanoscale optical imaging of excitons in single-walled carbon nanotubes.
We present simultaneous near-field photoluminescence (PL) and Raman imaging of single-walled carbon nanotubes (SWNTs) with a spatial resolution better than 15 nm. Highly localized excitation is used to visualize the spatial extent of the contributing excited states. For SWNTs on glass, we typically observe highly confined PL from short segments of about 20 nm in length. The PL from micelle-enca...
متن کاملUltrafast spectroscopy of excitons in single-walled carbon nanotubes.
We studied the femtosecond dynamics of photoexcitations in films containing semiconducting and metallic single-walled carbon nanotubes (SWNTs), using various pump-probe wavelengths and intensities. We found that confined excitons and charge carriers with subpicosecond dynamics dominate the ultrafast response in semiconducting and metallic SWNTs, respectively. Surprisingly, we also found from th...
متن کاملMicro-Photoluminescence Spectroscopy of Excitons in Individual Single-Walled Carbon Nanotubes
Single-walled carbon nanotubes (SWNTs) are fascinating materials to study onedimensional photophysics. Their optical properties are strongly affected by strong Coulomb interactions and are determined by ”excitons” which represent the quantum of polarization in non-metallic solids. In this thesis dissertation we have experimentally investigated both the structure and the dynamics of excitons in ...
متن کاملSingle - Walled 4 . Single - Walled Carbon Nanotubes
Single-walled carbon nanotubes (SWCNTs) are hollow, long cylinders with extremely large aspect ratios, made of one atomic sheet of carbon atoms in a honeycomb lattice. They possess extraordinary thermal, mechanical, and electrical properties and are considered as one of the most promising nanomaterials for applications and basic research. This chapter describes the structural, electronic, vibra...
