Abstract

In this paper, the optical properties investigated and the effect of the gamma irradiation on the optical constant in addition to the energy band gap (Eg) of Sudan black stain doped Poly Methyl Methacrylate (PMMA) thin films. Thin films of 20% Sudan black stain/PMMA doping ratio was used to prepared three concentrations (1, 0.7, 0.4) x10-3 M. all the Dye/ Polymer solution (three different concentrations) deposited on glass substrate by using a free casting method at room temperature.
