Abstract

For poly-N-epoxypropylcarbazole films doped with a cationic polymethine dye, the photoconductivity and the effect of an external electric field on photoluminescence intensity in the dopant absorption region have been found to depend on the nature of a colorless dye counter-ion. These effects have been accounted for by a changed probability of an intersystem crossing in dye ion pairs and photogenerated electron–hole pairs. The spin conversion rate has been related to the degree of photoluminescence quenching in an external electric field.
