Abstract
In this work the transmittance coefficient (T), the reflectance coefficient (R), the refractive index (n), the extinction coefficient (k), the optical absorption coefficient (a) and the optical band gap (Eof thin (poly[1-[4-(3-carboxy-4-hydroxyphenylazo) benzenesulfonamido]-1,2-ethanediyl, sodium salt]), shortly PAZO, azopolymer films with embedded particles of Cu(II) 3-amino-5,5‘-dimethylhydantoin at three different concentrations have been determined. The influence of the dopants concentration on the optical performance of the composite films has been discussed.
