Abstract: A simple equation is proposed for calculating the sensitized luminescence kinetics of acceptors caused by nonradiative excitation energy transfer (Förster Resonance Energy Transfer (FRET)) from donors. As parameters, the equation includes the lifetimes of the donor and acceptor excited states and the experimental luminescence decay kinetics of donors in the presence of FRET. The equation does not specify a certain FRET mechanism. It is proposed to use this equation to fit the experimental sensitized luminescence kinetics in order to quantitatively confirm the existence of FRET between donor and acceptors.

Keywords: nonradiative energy transfer, sensitized luminescence, luminescence decay kinetics.
