Influence of ionic forms of polymethine dyes on the photoconductivity of doped films of poly-N-epoxypropylcarbazole
Thr features of photoconductivity of the films of poly-N-epoxypropylcarbazole doped with cationic. squarylium and merocyanine dyes are investigated. Under temperature growth starting from room the photoconductivity of the films with cationic anti squarylium dyes increases more strongly as compared to the similar films with merocyanine. It was explained by a destruction of structural traps close to electrically charged fragments of dyes. In contrast to the films of the first two types, the photoconductivity of the films with merocyanine dye depends sublinearly on incident light intensity due to an effective bimolecular charges recombination.
