Observation of Enhanced Energy Transfer in Individual Quantum Dot-Oligophenylene Vinylene Nanostructures

摘要

Blends of conjugated organic polymers with inorganic quantum dots have received a great deal of recent attention for their potential in advanced optoelectronic devices and photovoltaic energy-harvesting applications.Among the interesting features of these composite systems is the electronic communication between conjugated organic and quantum dot or quantum rod components,which results in enhanced fluorescence quantum yields,energy transfer,and charge transport in bulk thin films." However,as noted by several authors,phase segregation of the organic and inorganic components becomes problematic when constructing efficient thin-film optoelectronic devices.
