Kinetics of triplet excitation transport in disordered organic solids
The time dependence of triplet excitation energy transport in energetically disordered organic solids is studied. Contrary to the ensemble averaged hopping frequency ν( t)∼ t α( t)−1 with time dependent dispersion parameter α( t), we introduce the hopping rate in the form ν( t)∼( a+ bt) −1, without...
