Journal ArticleDOI
Large scale, selective dispersion of long single-walled carbon nanotubes with high photoluminescence quantum yield by shear force mixing
Arko Graf,Yuriy Zakharko,Stefan P. Schießl,Claudia Backes,Moritz Pfohl,Moritz Pfohl,Benjamin S. Flavel,Jana Zaumseil +7 more
TL;DR: In this article, the authors used simple high speed shear force mixing (SFM) to disperse nearly monochiral (6,5) SWCNTs with poly[(9,9-dioctylfluorenyl-2,7-diyl)- alt - co-co-(6,6′-{2,2′-bipyridine})] (PFO-BPy) with high yield and in large volumes.
Journal ArticleDOI
Carbon Nanotube-Silicon Solar Cells
TL;DR: In this article, single-walled carbon nanotubes are used for photovoltaic devices. But they are not suitable for use in photophotonics, as they are an allotrope of carbon with unique electrical and optical properties.
Journal ArticleDOI
Cavity-enhanced light emission from electrically driven carbon nanotubes
Felix Pyatkov,Felix Pyatkov,Valentin Fütterling,Svetlana Khasminskaya,Benjamin S. Flavel,Frank Hennrich,Manfred M. Kappes,Ralph Krupke,Ralph Krupke,Wolfram H. P. Pernice,Wolfram H. P. Pernice +10 more
TL;DR: In this article, the authors demonstrate the use of carbon nanotubes as electrically driven high-speed emitters in combination with a nanophotonic cavity that allows for exceptionally narrow linewidths.
Journal ArticleDOI
Separation of single-walled carbon nanotubes by 1-dodecanol-mediated size-exclusion chromatography.
TL;DR: A simple, single-column, high-throughput fractionation procedure based on size-exclusion chromatography of aqueous sodium dodecyl sulfate suspensions of single-walled carbon nanotubes (SWCNTs) is presented and is found to yield monochiral or nearmonochiral SWCNT fractions of semiconducting SWC NTs.
Journal ArticleDOI
Separation of Single-Walled Carbon Nanotubes with a Gel Permeation Chromatography System
TL;DR: A gel permeation chromatography system is used to separate aqueous sodium dodecyl sulfate suspensions of single-walled carbon nanotubes (SWCNTs) and monochiral SWCNT fractions of semiconducting SWC NTs with a purity of 61-95%.
