Nanoscale optical imaging of single-walled carbon nanotubes

چکیده
In this contribution, we apply a microscopic technique that relies on the enhanced electric field near a sharp, laserirradiated metal tip that acts as a highly confined light source. The tip is used for the local excitation of the optical response of single-walled carbon nanotubes (SWNT) deposited on glass. We demonstrate photoluminescence and Raman imaging of the same SWNTs with a spatial resolution of about 10 nm. r 2006 Elsevier B.V. All rights reserved. PACS: 61.46.+w; 07.79. v; 78.30.Na; 78.67.Ch

Nanoscale 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 کاملMultimodal optical sensing and analyte specificity using single-walled carbon nanotubes.
Nanoscale sensing elements offer promise for single-molecule analyte detection in physically or biologically constrained environments. Single-walled carbon nanotubes have several advantages when used as optical sensors, such as photostable near-infrared emission for prolonged detection through biological media and single-molecule sensitivity. Molecular adsorption can be transduced into an optic...
متن کاملFlexible single-walled carbon nanotubes/polyaniline composite films and their enhanced thermoelectric properties.
Flexible single-walled carbon nanotubes/polyaniline (SWNT/PANi) composite films with enhanced thermoelectric properties were prepared via a simple method. Furthermore, these paper-like composite films show good flexibility, which makes them possible to be widely applied in various flexible energy converter devices.
متن کاملSize reduction of 3D-polymer-coated single-walled carbon nanotubes by ultracentrifugation.
We describe a novel single-walled carbon nanotube (SWNT) cutting method without introducing any structural defects on the tubes; namely, the finding that simple ultracentrifugation at 600 000g for the SWNTs coated with a cross-linked polymer formed by poly(N-isopropylacrylamide) (PNIPAM) or the polyethylene glycol-carrying PNIPAM copolymer provides shortened (<200 nm) SWNTs, which was revealed ...
متن کاملOxidative biodegradation of single- and multi-walled carbon nanotubes.
In this study we compare the biodegradation of both single-walled (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) using two different oxidative conditions. In particular, we demonstrate that oxidized multi-walled carbon nanotubes are highly degraded, although not to completeness when treated with horseradish peroxidase (HRP) in the presence of hydrogen peroxide.
