Decoherence, Master Equation for Open Quantum Systems, and the Subordination Theory
… This model can be used to describe intermittent fluorescence, as a sequence of "light on" and "light off" states. The experiments on blinking quantum dots indicate that the sojourn times are distributed with an inverse power law. Thus, a proposal to turn the model for Poisson fluorescence …

Excitation evolution and self-regulation ability of photosynthetic light-harvesting systems /
… in order to understand the processes of fluorescence intermittency and singlet–triplet annihilation, observed in single LHCII complexes. It is also demonstrated that the multi-exponential fluorescence decay kinetics, observed in various photosynthetic systems is just a manifestation of …

Investigating the unique occurrence of polytypism and the role of available shell precursors in the growth of giant shell quantum dots
… yields, increase photostability and suppress fluorescence intermittency (blinking) in ‘giant quantum dots’ (gQDs). These unique properties make gQDs excellent candidates for applications in lasers, single molecular probes and solid state LEDs. Although a growing wealth of knowledge exists for …

Optical studies of colloidal quantum dots : optical trapping with plasmonic nanoapertures and thermal recovery from photoinduced dimming
… to investigate processes involved in single QD fluorescence intermittency, or blinking. Specifically, the transition from a nonemissive QD to an emissive QD was investigated using controlled amounts of thermal energy to drive recovery from photoinduced dimming in QD ensembles. Nonlinear thermal …

Seeing the invisible : single molecule microscopy in the shortwave infrared
… nanocrystals emitting at 1100 nm and observe fluorescence intermittency (blinking) under continuous excitation. The extracted on/o waiting-time statistics were power-law distributed, with exponents nearly identical to those measured from visible NCs. In addition, we demonstrate the feasibility …

Single nanocrystal microscopy and spectroscopy unveils hidden mechanistic information in cation exchange
… dot nanocrystals undergoing cation exchange. The fluorescence-based individual nanocrystal reaction trajectories led to the finding that cation exchange is a cooperative reaction, which had yet to be observed in nanoscience. Chapter 3 describes the intermittent fluorescent emission of individual …
