Some Optical Parameters of PS Films Doped with CuO

Abstract

In the present work, we have studied the effect of CuO2 dopant on the optical properties of (Polystyrene) (PS) polymer. The CuO doped PS films were prepared using solvent casting method, optical energy band gap Eg was estimated by using UV-VI-NIR spectra and it was classified as an indirect allowed transition. In general Eg was found to decrease with the increasing of dopant concentration. The refractive indices of the samples were measured and it was found to increase with the increasing of dopant concentration. Optical transmittance, reflectance and extinction coefficient were also investigated and correlated with the action of doping process.
