Paper Abstract

The mobility of dye molecules in a polymer matrix was investigated by use of electroabsorption and dielectric relaxation spectroscopy. The electroabsorption spectroscopic method is selective to the relaxation processes of the chromophores embedded in a matrix. The technique can be used to determine the fast relaxation processes at higher temperatures which are not observable in time domain as well as for observation of slow processes below the glass transition point.
