چکیده

Abstract—The Förster Resonance Energy Transfer (FRET) studies between acridinedione dyes as donors and rhodamine dyes as acceptors are explored by spectroscopic techniques like absorption, fluorescence and lifetime measurements. Enhancement of the acceptor photoluminescence intensity and a decrease of the donor decay time are observed in solutions containing acridinedione dye with Rhodamine B (Rh-B). The Förster parameters were calculated and were found to well correlate with the experimental findings. The evidence for the emergence of acridinedione dyes as good energy donors was observed from the high efficiency of energy transfer obtained from fluorescence lifetime measurements and high rate constants obtained from Stern-Volmer calculations.

Förster transfer outside the weak-excitation limit

The efficiency of resonance energy transfer can be used to determine nanometer-scale separations between dye molecules in a donor-acceptor pair. We argue that the standard method for making this determination in single-pair experiments is valid only when excitation by the applied field is much slower than the other photophysical processes in the system. We derive a simple relation between measu...
