Using local environmental effects in dye doped polymeric thin films

In order to improve the efficiency of optical polymers' function in photonic applications, the effect of local environment on small molecules of Disperse Red 1 and their dynamic behavior is studied. Poly Styrene Sulfonic Acid polymer used as host material to make highly doped polymeric thin films. By studying the samples' spectra in vitro and in situ, and investigating the photo-anisotropic effects on samples, it is shown that dye-polymer interaction can be the dominant factor in local environment around the dye molecules. Therefore, it can be used to increase significantly the response intensity and improve the performance of photonic devices.
