Energy transfer interactions with single molecule phenomena in small clusters of quantum dots
MetadataShow full item record
This dissertation describes the observed interactions between energy transfer in small clusters of nominally monodisperse semiconductor nanocrystals (quantum dots, QDs) and single molecule phenomena such as fluorescence intermittency (blinking) and antibunching. The relevant literature on energy transfer between QDs has typically invoked the Förster energy transfer mechanism to explain the observations in ensemble measurements. The size dispersion in QDs results in a dispersion in the electronic and optical properties of QDs due to size dependent confinement effects on photogenerated carriers. ...
