Fluorescence has been observed directly across the band gap of semiconducting carbon nanotubes. We obtained individual nanotubes, each encased in a cylindrical micelle, by ultrasonically agitating an aqueous dispersion of raw single-walled carbon nanotubes in sodium dodecyl sulfate and then centrifuging to remove tube bundles, ropes, and residual catalyst. Aggregation of nanotubes into bundles otherwise quenches the fluorescence through interactions with metallic tubes and substantially… 

Bright fluorescence from individual single-walled carbon nanotubes.

This work has found significant increases in the fluorescence efficiency of individual DNA-wrapped SWNTs upon addition of reducing agents, including dithiothreitol, Trolox, and β-mercaptoethanol.

Photoluminescence from Exciton Energy Transfer of Single-Walled Carbon Nanotube Bundles Dispersed in Ionic Liquids

Single-walled carbon nanotubes (SWNTs) can be dispersed into fine bundles in imidazolium-based ionic liquids (ILs) by simple mechanical grinding. Photoluminescence (PL) of the exciton energy

Highly selective dispersion of single-walled carbon nanotubes using aromatic polymers.

A dramatic improvement in the preparation of single-walled carbon nanotubes solutions based on the ability of specific aromatic polymers to efficiently disperse certain nanotube species with a high degree of selectivity is reported.

Structure-Assigned Optical Spectra of Single-Walled Carbon Nanotubes

Optical spectroscopy can be used to rapidly determine the detailed composition of bulk SWNT samples, providing distributions in both tube diameter and chiral angle.

Brightly Fluorescent Single-Walled Carbon Nanotubes via an Oxygen-Excluding Surfactant Organization

It is found that an aliphatic (dodecyl) analog of flavin mononucleotide, FC12, leads to high dispersion of SWNTs, which tend to aggregate into bundles, which led to quantum yields as high as 20%.

Environmental and synthesis-dependent luminescence properties of individual single-walled carbon nanotubes.

Influence of Polymer Electronics on Selective Dispersion of Single-Walled Carbon Nanotubes.

Nanotube dispersions with a poly(fluorene-co-pyridine) copolymer and its cationic methylated derivative are reported and it is shown that electron-deficient conjugated π-systems bias the dispersion selectivity toward metallic SWNTs.

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.



Stabilization of Individual Carbon Nanotubes in Aqueous Solutions

Single-wall carbon nanotubes pack into crystalline ropes that aggregate into tangled networks due to strong van der Waals attraction. Aggregation acts as an obstacle to most applications, and
