We present fluorescence decay measurements of single ZnS covered CdSe nanocrystals. It
is shown that the fluorescence decay time is fluctuating during the investigation leading to a …

Colloidal semiconductor nanocrystals, combine the physical and chemical properties of
molecules with the optoelectronic properties of semiconductors. Their colour is highly …

We present a new physical model resolving a long-standing mystery of the power-law
distributions of the blinking times in single colloidal quantum dot fluorescence. The model …

The origin of photoluminescence in carbon dots has baffled scientists since its discovery. We
show that the photoluminescence spectra of carbon dots are inhomogeneously broadened …

Interacting many-body systems are characterized by stable configurations of objects—
ranging from elementary particles to cosmological formations,,—that also act as building …

By means of photoluminescence spectroscopy we compare the bias dependent emissions
of single quantum dots which are embedded in two differently designed photodiode …

Picosecond and femtosecond spectroscopy allow the detailed study of carrier dynamics in
nanostructured materials. In such experiments, a laser pulse normally excites several …

Chemically synthesized semiconductor quantum dots (QDs) can potentially enable solution-
processable laser diodes with a wide range of operational wavelengths, yet demonstrations …

Take some crystals of cadmium selenide, measuring a just few billionths of a metre across,
add an ordinary microscope, and what have you got? According to a small but growing band …

A simple model explaining the experimental data on QDs luminescence blinking is
suggested. The model does not assume the presence of the long-lived electron traps. The …
