Control of Energy-Transfer Efficiency in a Hybrid System of a Wide-bandgap Conjugated Polymer and Quantum Dots |
| 초록 |
We prepared a hybrid system composed of a wide-bandgap congugated polymer (PBDB-T) and CdSe/CdS core-shell quantum dots (QDs) using chlorobenzene (CB) and an additive solvent. We found that the nanostructure of the PBDB-T domains has a significant effect on energy-transfer from the CdSe/CdS QDs to PBDB-T in the hybrid thin film. To clarify the photoluminescene-enhancement mechanism in the hybrid film induced by the energy-transfer from the QDs to PBDB-T, we analyzed the time-resolved absorption data of the hybrid film with our proposed kinetic models. Our findings of the hybrid system may provide important information that can be used to increase the efficiency of the optoelectronic devices. |
