Abstract:
Förster resonant energy transfer (FRET) between the CdTe quantum dot (QD) acting as donors and acceptors is
investigated at nanoscale proximity to gold nanoparticles (Au NPs). Photoluminescence (PL) studies of the acceptor QD
emission from a mixed monolayer showed a distance dependent enhancement of the acceptor emission compared with
that achieved for a donor-acceptor mixed monolayer in the absence of the Au NP layer. Time-resolved
photoluminescence measurements showing a reduction in the donor lifetime, accompanied by an increase in the acceptor
PL lifetime, provide further evidence for surface plasmon enhanced FRET.
