When compared to standard colloidal nanocrystals, individual CdSe-CdS core-shell
nanocrystals with thick shells exhibit strongly reduced blinking. Analyzing the photon …

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 …

Semiconductor nanocrystals emit light intermittently; ie, they “blink,” under steady
illumination. The dark periods have been widely assumed to be due to photoluminescence …

The spectroscopy and dynamics of multiple excitations on colloidal type-II Cd Te∕ Cd Se
core-shell quantum dots (QDs) are explored via quasi-cw multiexciton spectroscopy. The …
