Simulation of the phosphorescence decay kinetics of donor molecules of matrix-isolated donor—acceptor pairs

Abstract

The phosphorescence decay kinetics of triplet excitations being energy donors in matrix-isolated donor—acceptor pairs has been analyzed using numerical simulation. It has been noted that the inclusion of states of donor—acceptor pairs in which both molecules are in the triplet state during energy transfer can have an effect on the phosphorescence decay kinetics of donor molecules and its dependence on the excitation power
