Abstract

The dielectric function of poly 2-methoxy-5-hexyloxyl phenylenevinylene and alternating copolymers with N-hexyphenothiazine grown on glass using Raman spectroscopy was investigated. The dielectric function of each polymer, band gap parameters such as threshold energy, broadening and amplitude were determined using parametric optical constant model. The band gap parameters were also determined by performing lineshape curve-fitting on second derivative of the fit dielectric function using standard critical point model. The fitting of dielectric functions and their derivatives show appropriate band structure for poly(p-phenylene vinylene) (PPV) derivatives.
