摘要
Coherent molecular excitations in Scheibe aggregates are investigated in a quantum framework by using the non-linear Schrodinger equation with radial symmetry. An interpretation of the characteristic distance for the energy transfer between donors and acceptors on the film is given in terms of the maximum radius of a quantum ring wave. The corresponding lifetime of the coherent excitations is found to be in agreement with measurements.
