Journal ArticleDOI
Bright band gap photoluminescence from unprocessed single-walled carbon nanotubes.
TL;DR: A strong enhancement of photoluminescence intensity is observed when the excitation wavelength is resonant with the second Van Hove singularity, unambiguously confirming the origin of the photol Luminescence.
Journal ArticleDOI
Photoluminescence imaging of suspended single-walled carbon nanotubes.
TL;DR: Most SWNTs imaged on millisecond time scales show steady emission, but a few fluctuate and suffer a reduction of intensity, and quantum efficiency is dramatically higher than that in previous reports.
Journal ArticleDOI
Photoluminescence from an individual single-walled carbon nanotube
TL;DR: In this paper, single-walled carbon nanotubes (SWNTs) were compared with spectra from ensembles, showing that the peak shape and peak width are almost the same for a single nanotube as they are for the corresponding species in a large ensemble.
Journal ArticleDOI
Photoluminescence from single-walled carbon nanotubes: a comparison between suspended and micelle-encapsulated nanotubes
TL;DR: In this article, the authors compared the spectral properties of single-walled carbon nanotubes (SWNTs) suspended in air between pillars, and found that emission peaks are blueshifted by 28 meV on average for the suspended SWNTs as compared to the encapsulated ones.
Journal ArticleDOI

TL;DR: How an easily scalable technique provides large-diameter sc- SWCNTs with high purity is demonstrated, further enabling the best TFT performance reported to date for conjugated polymer enriched sc-SWC NTs.
