Abstract:
We report highly efficient Forster resonance energy transfer between CdTe nanocrystals and two different dyes,
Rhodamine B and Oxazine, where the nanocrystals are mixed with the dyes on top of glass substrates. A faster NC
decay curve is observed in the samples containing NCs mixed with dyes than in those containing NCs on their own. For
the samples containing nanocrystals mixed with Rhodamine B, room temperature PL measurements are presented as a
function of the ratio between the amount of acceptors and the amount of donors, CA/CD. This ratio is varied between
0.03 and 5. The strongest enhancement of the acceptor PL intensity relative to that of the donor PL intensity is reached
for 0.2 < CA/CD < 5, suggesting that most efficient FRET is also achieved in this region.
