The field of nanocrystal quantum dots (QDs) is already more than 30 years old, and yet
continuing interest in these structures is driven by both the fascinating physics emerging …

Multicarrier dynamics play an essential role in quantum dot photophysics and
photochemistry, and they are primarily governed by nonradiative Auger processes. Auger …

The ability to confine electrons and holes in semiconductor quantum dots (QDs) in the form
of excitons creates an electronic structure which is both novel and potentially useful for a …

Charged exciton states commonly occur both in spectroscopic studies of quantum dots
(QDs) and during operation of QD-based devices. The extra charge added to the neutral …

We report the first experimental observation of a striking convergence of Auger
recombination rates in nanocrystals of both direct-(InAs, PbSe, CdSe) and indirect-gap (Ge) …

Lead halide perovskite nanocrystals (NCs) hold strong promise for a variety of light‐
harvesting, emitting, and detecting applications, all of which, however, could be complicated …

Using charged films of colloidal CdSe/CdS core/shell quantum dots of∼ 3.5 to 4.5 nm core
diameters and 0.6 to 1.2 nm thick CdS shells, the radiative and nonradiative decay of the …
