摘要
We have experimentally studied optical limiting in multi-component solutions containing polycyclic compounds (perylene and fallerenes) for which typical processe 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.
