Organic – Inorganic Nanostructure Architecture via Directly Capping Fullerenes onto Quantum Dots

View Article: PubMed Central - HTML - PubMed

ABSTRACT

Pcba: A new form of fullerene-capped CdSe nanoparticles (-capped CdSe NPs), using carboxylate ligands with [60]fullerene capping groups that provides an effective synthetic methodology to attach fullerenes noncovalently to CdSe, is presented for usage in nanotechnology and photoelectric fields. Interestingly, either the internal charge transfer or the energy transfer in the hybrid material contributes to photoluminescence (PL) quenching of the CdSe moieties.

Mentions: The UV–Vis and photoluminescence (PL) properties of all the NPs (HDA-capped CdSe, pyridine-capped CdSe and PCBA-capped CdSe) were investigated in chloroform solution. As shown in Figure 3, the solution optical spectra of both HDA-capped CdSe and pyridine-capped CdSe exhibit broad absorption bands (410–460 nm), arising from exciton absorption peak in CdSe NPs. In the case of PCBA-capped CdSe, the distinguishable band at 330 nm corresponds to the characteristic of C60 not only exhibits but also the absorption feature is almost identical to that of the pristine PCBA. This implies that PCBA is completely binding along the CdSe unit.
