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.

Figure 1: Synthesis of PCBA-capped CdSe NPs.

Mentions: In the current work, through the ligand-exchange reaction, we describe here a route to prepare readily soluble nanocomposite of PCBA-CdSe (Figure 1). The structural and spectroscopic properties of the resulting PCBA-capped CdSe nanoparticles (NPs) are of great interest since such rational design and synthesis can lead potentially to promising protocol for use in optical and photoelectric fields. Either the internal charge transfer or the energy transfer phenomenon between CdSe core and PCBA shell is clearly observed, resulting in the photoluminescence (PL) quenching of CdSe.
