Abstract

A series of CdSe elongated NCs (quantum rods) were used to study the effect of the 0D to 1D transition on nonradiative Auger recombination. A transition from cubic to quadratic decay was observed as the rod aspect ratio is increased above ∼8. It was found that the use of elongated NCs allow to reduce nonradiative carrier losses arising from Auger recombination compared to spherical NC emitting at the same wavelength.
