In this review, we discuss investigations of electronic excitation energy transfer in
conjugated organic materials at the bulk and single molecule level and applications of …

Polarization spectroscopy of single fluorescent molecules is used to probe their rotational
dynamics. When a molecule is immobilized on a dry surface, its in-plane dipole orientation is …

In the last decade emerging single‐molecule fluorescence‐spectroscopy tools have been
developed and adapted to analyze individual molecules under various conditions. Single …

We present the first demonstration that fluorescence resonance energy transfer can be used
to track the motion of a single molecule undergoing conformational changes. As a model …

Colloidal quantum dots (QDs) have attracted extensive attention due to their excellent
optoelectronic properties, such as high quantum efficiency, narrow emission peaks, high …

Single-molecule spectroscopy of well-chosen dendritic multichromophoric systems allows
investigation of fundamental photophysical processes such as energy or electron transfer in …

The distance (R DA) and orientation dependence of the rate for electronic excitation transfer
(EET) from a segment of polyfluorene (PF6) to tetraphenylporphyrin (TPP) is studied using …

Single light-harvesting complexes LH-2 from Rhodopseudomonas acidophila were
immobilized on various charged surfaces under physiological conditions. Polarized light …

The on–off intermittent behavior of emission from single CdSe/CdS core/shell nanocrystals
was investigated as a function of temperature and excitation intensity. Off times were found …

Carbon nanotubes have two major assets for potential technological applications: their
electronic properties and their extremely high mechanical strength, which make them …
