Photoluminescence blinking—random switching between states of high (ON) and low (OFF)
emissivities—is a universal property of molecular emitters found in dyes, polymers …

Nanocrystal quantum dots are attractive materials for applications as nanoscale light
sources. One impediment to these applications is fluctuations of single-dot emission …

The photoluminescence from a variety of individual molecules and nanometre-sized
crystallites is defined by large intensity fluctuations, known as 'blinking', whereby their …

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

Fluorescence blinking in nanocrystal quantum dots is known to exhibit power-law dynamics,
and several different mechanisms have been proposed to explain this behavior. We have …

SEMICONDUCTOR nanocrystals offer the opportunity to study the evolution of bulk
materials properties as the size of a system increases from the molecular scale1, 2. In …

Semiconductor nanocrystals offer an enormous diversity of potential device applications,
based on their size-tunable photoluminescence, high optical stability and'bottom …

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