Near-infrared emission quantum yield of soluble short single-walled carbon nanotubes.

Abstract

Soluble short single-walled carbon nanotubes in aerated D(2)O emit in the near-infrared (NIR) region [picture: see text] with a quantum yield of (3.9+/-0.5) x10(-3) and a half-life of 7.65 micros. This emission is quenched by electron- acceptor molecules. Soluble short single-walled carbon nanotubes (sSWNT) are prepared by means of chemical fragmentation… (More)
