Reversible Electrochemical Control over Photoexcited Luminescence of Core/Shell CdSe/ZnS Quantum Dot Film

Semiconductor quantum dots (QDs) are widely used in light-emitting diodes and solar cells. Electrochemical modulation is a good way to understand the electrical and optical properties of QDs. In this work, the effects of electrochemical control on photoluminescence (PL) spectra in core/shell CdSe/ZnS QD films are studied. The results show different spectral responses for surface emission and co...

Single dot luminescence characteristics of CdSe/ZnS core-shell structured quantum dots with different ligands

Chemical derivatizations with different ligands were perfomed on CdSe/ZnS core-shell quantum dots (QDs). The ligands serve a role to increase water solubility and bio-compatibility of QDs in the application of in vivo biomedical fluorescence imaging. These QDs were synthesized with various capping agents and optically characterized by using single molecule detection technique to investigate the...

Spin Polarized Current Generation from Quantum Dots without Magnetic Fields

Gating of hole transfer from photoexcited PbS quantum dots to aminoferrocene by the ligand shell of the dots.

Photoinduced hole transfer from PbS quantum dots (QDs) to aminoferrocene only occurs if the ligand shell of the QD allows aminoferrocene to gain direct access to the inorganic core of the QD; the permeability of the ligand shell is therefore more important than its conductivity in determining the probability of interfacial charge transfer.
