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

Metal halide perovskites are highly attractive for lighting applications, but the multiexcitonic
emission processes in these crystals are largely unexplored. This study presents an …

The cylindrical quasi-one-dimensional shape of colloidal semiconductor nanorods (NRs)
gives them unique electronic structure and optical properties. In addition to the band gap …

Biexciton emission in quantum dots is an efficient way to generate entangled photon pairs,
which are key resources in quantum informatics. Compared with epitaxial grown quantum …

Most experiments on multiexcitons (MX) in quantum dots focused on the biexciton (XX),
which is now well-understood. In contrast, there is little understanding of higher MX in …

Metal halide perovskite nanocrystals are under intense investigation for their outstanding
optical and electronic properties. The presence of higher fine structure states, let alone …

Hot electrons can dramatically improve the efficiency of solar cells and sensitize
energetically-demanding photochemical reactions. Efficient hot electron devices have been …

Photoluminescence intermittency is a ubiquitous phenomenon, reducing the temporal
emission intensity stability of single colloidal quantum dots (QDs) and the emission quantum …

We monitor the time-resolved photoluminescence (t-PL) from CsPbBr3 perovskite
nanocrystals with a time resolution of 3 ps, which is fast enough to resolve emission from …

Correlations between excitons, that is, electron–hole pairs, have a great impact on the
optoelectronic properties of semiconductor quantum dots and thus are relevant for …
