Determination of amines based on their interaction with QDs: Effect of the formation QD-assemblies

Analytica Chimica Acta, 2011
Assemblies of closed nanoparticles have focused interest because they exhibit new optical and chemical properties. The use of a 1D covalent strategy for quantum dots-assemblies has been proposed in this work as novelty. It was studied the effect of use different dithiols, including aromatic and aliphatic dithiol compounds, on the formation of QDs ...

Effects of QD Concentrations and Thermal Annealing on the Performance of Self-Assembly QD-OLEDs

Journal of Nanoscience and Nanotechnology, 2011
We have fabricated and investigated the effect of CdSe/ZnS quantum dot (QD) concentrations on the performance of self-assembly hybrid inorganic/organic light emitting diodes (QD-OLEDs). The uniform distribution of QDs with controllable density was achieved using the conventional spin-coating method.
