Effect of constant electric field on electronic absorption spectra of dye-doped amorphous polymer films

Effect of constant electric field on electronic absorption spectra of dye-doped amorphous polymer films

The change of an electronic absorption coefficient of polymer films, doped by symmetric cationic polymethine dye is researched in an external constant electric field. This effect are characterised by an increase of intensity on the shortwave edge of a band and its decrease at the longwave edge. The...
