The mystery of blinking dots

Pavel Frantsuzov
Department of Physics, University of Notre Dame

A striking puzzle was raised eight years ago by the spectroscopic experiments on single colloidal quantum dots (QDs). The emission intensity of the single QD under the continuous excitation intensively switches on and off (blinks). The distribution of the duration times has the power law behavior over 6 decades of time. This behavior is unchanged for the different temperatures, radii, laser intensities, materials, and atmospheric conditions. The discovery of the molecular mechanism of such long-correlated phenomena in single nanoparticle represents a great challenge. I intend to present the history of solving this amazing puzzle which looks like something out of a detective novel.
