Publikováno v: Physical Chemistry Chemical Physics
Physical Chemistry Chemical Physics, 2021, 24 (3), pp.1787-1794. ⟨10.1039/D1CP04260B⟩
A macroscopic model of exciton density decays in disordered molecular systems, including contributions from molecular aggregate quenchers, is proposed. The model can be applied to ultrafast decays of dyes and for global fitting of experimental data.
