Synthesis and Applications of Organic-Quantum Dot Hybrid Materials |
| 초록 |
In this work our attempts to prepare a hybrid material of semiconducting nanocrystal quantum dots (DQs) and polystyrene are explained. Previously organic memory cell devices have been reported with Au nanoparticles showing very high performances. CdSe QDs appear to possess the required fundamental properties to be used in such hybrid QD/polymer devices; attempts to date in this regard are none to our best knowledge. We report here the memory characteristics of an organic memory device with CdSe/ZnS QDs having cabazole based organic ligands blended with polystyrene deposited on aluminum substrates. Ligand selection was crucial because QDs with oleic acid ligands were practically unable to spread QDs uniformly throughout the QD:PS blend. The carbazole based ligands having alkyl substituents of different chain lengths presently used in this study successfully dispersed QDs uniformly throughout the blend. |
