Abstract:
The external magnetic field effects on the spectral and luminescent properties of film composites based on photoconductive poly(N epoxypropylcarbazole) doped with cationic polymethine and merocya nine dyes have been studied. The magnetic field effects on the intensity and kinetics of delayed fluorescence and recombination luminescence have been revealed. These effects are explained by participation in the pho togeneration of charged pairs of singlet–triplet intersystem crossing in excited dye molecules.
