FORWARD AND REVERSE ELECTRONIC-ENERGY TRANSPORT AND TRAPPING IN SOLUTION .1. THEORY

A theoretical study of forward and reverse incoherent transport and tr apping of electronic excitations in a two-component disordered system is carried out. The method used is the diagrammatic expansion of the c onfiguration averaged Green function of the master equation for this p roblem. A new summation method based on the fractal structure of multi graphs with nodes allowing the calculation of the investigated infinit e series is introduced. The results of an exact diagrammatic analysis are presented. The donor fluorescence decay function, relative quantum yield and emission anisotropy are obtained using the self-consistent approximation.
