Fluorescence of electron donor-acceptor pairs of N-ethylcarbazole and 1,3-dicyanobenzene in the presence of electric field and magnetic field

The mechanism of the synergy effect of the electric field and magnetic field on fluorescence. The energy separation between the fluorescent state and the radical-ion state (RIP) is affected by electric fields and the singlet and triplet interaction of RIP is affected by magnetic field, resulting in the synergy effect on fluorescence.
