Photoluminescence from intertube carrier migration in single-walled carbon nanotube bundles.

چکیده
Photoluminescence (PL) identifies spectroscopic signatures of intertube transfer of optically pumped carriers in single-walled carbon nanotube (SWNT) ensembles. Resonant photoexcitation of large band gap SWNTs produces strong PL from smaller band gap SWNTs. Magnetic alignment measurements associate the energy-transfer PL peaks with the formation of SWNT bundles, suggesting that efficient coupling results from physical contact.

Carrier transport properties in single-walled carbon nanotubes studied by photoluminescence spectroscopy
We have investigated the photoluminescence (PL) of in individual single-walled carbon nanotubes (SWNTs) placed in field-effect transistor structures to study carrier transport in the SWNT. The relation between the recombination lifetime and carrier transit time has been evaluated from the drain-field dependence of PL intensity. Time-resolved photoluminescence of SWNTs dispersed in surfactant so...
متن کاملPhonon density of states of single-wall carbon nanotubes
The vibrational density of states of single-wall carbon nanotubes (SWNT) was obtained from inelastic neutron scattering data from 0 to 225 meV. The spectrum is similar to that of graphite above 40 meV, while intratube features are clearly observed at 22 and 36 meV. An unusual energy dependence below 10 meV is assigned to contributions from intertube modes in the 2D triangular lattice of SWNT bu...

We introduce intertube interactions of a cantilevered triple-walled carbon-nanotube (TWCNT) resonators via classical molecular dynamics simulations. The fundamental frequencies of TWCNT resonators were less than those of singleand double-walled carbon nanotubes of a given diameter because of the increasing intertube disturbance. Our results imply that for a nanotube with a given diameter, the f...
متن کاملOptical properties of nanotube bundles by photoluminescence excitation and absorption spectroscopy
Photoluminescence excitation (PLE) and absorption spectroscopy are applied to investigate the impact of bundle size on the optical properties of single wall carbon nanotube (SWNT) bundles in aqueous suspensions. The existence and gradual formation of small bundles happens in aqueous suspensions even after ultrasonication and ultracentrifugation. With time, the emission and absorption spectra sh...
متن کاملReinforcement of single-walled carbon nanotube bundles by intertube bridging.
During their production, single-walled carbon nanotubes form bundles. Owing to the weak van der Waals interaction that holds them together in the bundle, the tubes can easily slide on each other, resulting in a shear modulus comparable to that of graphite. This low shear modulus is also a major obstacle in the fabrication of macroscopic fibres composed of carbon nanotubes. Here, we have introdu...
