Influence of Radical Ions on Optical Limiting Effect in Solutions of Polycyclic Compounds

摘要

We have experimentally studied optical limiting in multi-component solutions containing polycyclic compounds (perylene and fullerenes) for which typical pfocesse is photoinduced electron transfer with formation of ion pairs. Founded significant rise of limiting efficiency in such molecular systems is due to increase of absorption in the excited state. Formation of radical ions can be used for widening of spectral range of operating medium limiting.
