Many potential applications of quantum dots (QDs) can only be realized once the
luminescence from single nanocrystals (NCs) is understood. These applications include the …

Abstract 'Blinking', or 'fluorescence intermittency', refers to a random switching between
'ON'(bright) and 'OFF'(dark) states of an emitter; it has been studied widely in zero …

Single-photon sources are essential for advancing quantum technologies with scalable
integration being a crucial requirement. To date, deterministic positioning of single-photon …

Photonic quantum information requires high-purity, easily accessible, and scalable single-
photon sources. Here, we report an electrically driven single-photon source based on …

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 …

Many optoelectronic processes in colloidal semiconductor nanocrystals (NCs) suffer an
efficiency decline under high-intensity excitation. This issue is caused by Auger …
