Abstract:
The subject of investigation is poly-$N$-epoxypropylcarbazole and poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene-vinylene] films with zinc 2,3,9,10,16,17,23,24-octabutylphthalocyanine additives. The photoconducive and photodielectric properties of these heterostructures are studied in the absorption range of the metal complex. The photosensitivity of the structures depends on the triplet state of photogenerated electron-hole pairs, their dissociation in an external electric field, and charge carrier trapping. The increased photosensitivity of the heterostructures compared with that of constituent films is explained by a higher efficiency of dissociation of the photogenerated electron-hole pairs and a reduced influence of non-equilibrium carrier traps at the interfaces.
