Fluctuation kinetics of the hopping fluorescence quenching in disordered solid solutions: A theoretical model and experimental evidence

► Fluctuation kinetics of the hopping fluorescence quenching. ► We take a disordered solid solution of [Y1−xTbx(pyca)3(H2O)2]nH2O as chromophore. ► Measured kinetics is of Förster type but with large decay amplitude. ► CTRW approach for the analysis of the energy transfer kinetics. ► Discuss methods for determination of energy transfer microparameters.
