Role of triplet states of polymethine dyes in photogeneration of electron-hole pairs in poly(N-epoxypropylcarbazole) films

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 merocyanine 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 photogeneration of charged pairs of singlet-triplet intersystem crossing in excited dye molecules.
