Gotta love it.
Of course the entire article is way over my head with the excitons and dimensional state and whatnot.
But it certainly shows the potential of carbon nanotubes.
Especially in the infra red which, as the article points out, would help reduce the need for certain elements in the use of fiber optics.
Carbon nanotubes have the potential to function as light-emitting devices, which could lead to a variety of nanophotonics applications. However,
nanotubes currently have a low luminescence quantum yield, typically around 1%, which is restricted by their one-dimensional nature. In a new study,
scientists have demonstrated that artificially modifying the dimensionality of carbon nanotubes by doping them with zero-dimensional states can
increase their luminosity to 18%. The findings could lead to the development of nanophotonics devices such as a near-infrared single-photon emitter
that operates at room temperature.
