摘要:

The exciton trapping mechanism by impurity centers in quasi-1D molecular chains (J-aggregates) is studied for the binary solutions of dimethylformamide and water. It is determined that the exciton energy transfer is occurring due to the dipole-dipole mechanism. The influence of the exciton self-trapping process on the trapping efficiency was found. It is shown that the exciton trapping occurs mainly owing to free excitons. The critical radius and trapping rate were determined.
