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

Because of the strong spatial confinement of electronic wave functions and reduced
dielectric screening, the effects of carrier-carrier Coulomb interactions are greatly enhanced …

Coherent coupling between plasmons and transition dipole moments in emitters can lead to
two distinct spectral effects: vacuum Rabi splitting at strong coupling strengths, and induced …

Colloidal quantum dots exhibit efficient photoluminescence with widely tunable bandgaps
as a result of quantum confinement effects. Such quantum dots are emerging as an …

There have been multiple demonstrations of amplified spontaneous emission (ASE) and
lasing using colloidal semiconductor nanocrystals. However, it has been proven difficult to …

The use of colloidal semiconductor nanocrystals for optical amplification and lasing has
been limited by the need for high input power densities. Here we show that colloidal …

The quantum dot, one of the central materials in nanoscience, is a semiconductor crystal
with a physical size on the nanometer length scale. It is often called an “artificial atom” …

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 …

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

Engineering semiconductors to enhance carrier multiplication (CM) could lead to increased
photovoltaic cell performance and a significant widening of the materials range suitable for …
