Synthesizing and determining the optical properties and the surface, volume energy loss function of novel azo dye polymer (PHPP)


In this paper, azo dye polymer materials were synthesized from aniline with Novolac by Fox method. The fundamental optical constants of PHPP film measured at thickness 5μm film have been calculated by depending on the curve of absorption and transition spectra over the spectral of 300-900 nm in the room temperature. The energy gap was valued 4.176 eV. Finally, the interband transition strength, surface and volume energy loss function have been obtained depending on dielectric constant of the film.
