Abstract	Growth of concentration of the anion polymethine dye in the films of poly-N-epoxypropylcarbazole involves increase of quenching of photoluminescence in external electric field as well as appearance of longwave band of the photoluminescence and photoconductivity within visible spectral range. It was ascertained that associates of ionic pairs of the dye arise when the concentration increases. Anomalous for semiconductor materials kinetics of the photocurrent growth and relaxation was observed in the films of these composites: time of the photocurrent growth is much less than the time of its relaxation after the light is switched off. Effect of memory of preliminary illumination with light was observed in the films. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35274
