A telecom band single-photon source using a grafted carbon nanotube coupled to a fiber Fabry-Perot cavity in the Purcell regime
Antoine Borel, Théo Habrant-Claude, Federico Rapisarda +4
We report on the coupling of a reconfigurable high Q fiber micro-cavity to an organic color center grafted to a carbon nanotube for telecom wavelength emission of single photons in…
Enhanced single photon emission from carbon nanotube dopant states coupled to silicon microcavities
A. Ishii, X. He, N. F. Hartmann +4
Single-walled carbon nanotubes are a promising material as quantum light sources at room temperature and as nanoscale light sources for integrated photonic circuits on silicon. Her…
Generation of photoluminescent ultrashort carbon nanotubes through nanoscale exciton localization at sp3 -defect sites
Noémie Danné, Mijin Kim, Antoine Godin +8
The intrinsic near-infrared photoluminescence observed in long single walled carbon nanotubes is systematically quenched in ultrashort single-walled carbon nanotubes (usCNTs, below…
Dipolar and charged localized excitons in carbon nanotubes
Jan T. Glückert, Lyudmyla Adamska, Wolfgang Schinner +4
We study both experimentally and theoretically the fundamental interplay of exciton localization and polarization in semiconducting single-walled carbon nanotubes. From Stark spect…

We have used post-synthesis separation methods based on density gradient ultracentrifugation and DNA-based ion-exchange chromatography to produce aqueous suspensions strongly enric…
Multi-particle Auger dissociation of excitons in shallow doped carbon nanotubes
Jay D. Sau, Jared J. Crochet, Miguel Dimas +3
Shallow hole-doping in small diameter single-wall carbon nanotubes by HO is shown to result in delocalized excited state quenching with no effects on the ground state absor…
The Unique Origin of Colors of Armchair Carbon Nanotubes
E. H. Haroz, B. Y. Lu, P. Nikolaev +3
The colors of suspended metallic colloidal particles are determined by their size-dependent plasma resonance, while those of semiconducting colloidal particles are determined by th…
A New Route to Fluorescent SWNT/Silica Nanocomposites: Balancing Fluorescence Intensity and Environmental Sensitivity
