Nanoscale optoelectronic properties of organic p-n junction P3HT/PCBM nanoparticles hybridized with CdSe/ZnS quantum dots |
| 초록 |
Organic p-n junction nanoparticles (NPs) of P-type poly (3-hexylthiophene) (P3HT) and n-type[6, 6]-Phenyl C61-butyric acid methylester (PCBM) with approximate to diameters of 80-250nm were fabricated by mini-emulsion method. Various concentrations functionalized CdSe/ZnS quantum dots were hybridized with P3HT/PCBM NPs.The photoluminescence spectra of the QDs mostly overlapped the absorption spectra of the P3HT/PCBM NPs,suggesting the activation of energy or charge-transfer effects. Using a high-resolution laser confocal microscope (LCM), we observed that the LCM PL intensity of a single P3HT/PCBM NP quenched with increasing QD concentration.Conducting atomic force microscopy revealed that the photocurrent of the P3HT/PCBM NP was enhanced as the QD concentration increased. After the hybridization of the P3HT/PCBM NPs with the QD, the energy/charge-transfer effects and the charge dissociation of excitons with incident light have been more active, resulting in the increased photocurrent. |
