Abstract
The effect of composition on resonance energy transfer between CdxZn1-xS quantum dot (donor) and Nile red dye (acceptor) is studied by steady state and time-resolved spectroscopy. The energy transfer efficiency varies from 14% to 47% with change in the composition from Cd0.31Zn0.69S to Cd0.62Zn0.38S nanocrystals which follows the Förster resonance energy transfer process. Considering single donor and multiple acceptors interactions, the calculated average distances (rn) between donor and acceptor are 25.8, 31.6, and 39.9Å for Cd0.62Zn0.38S, Cd0.52Zn0.48S, and Cd0.31Zn0.69S nanocrystals, respectively.
