| Abstract: | Abstract The optical absorption spectra of polyvinyle chloride, PVC, doped with Cd and Pb is presented. The effect of γ radiation doses in range of 2–200 Mrad on the fundamental absorption edge Λg was determined. On the basis of quantitative analysis of obtained data, the calculated absorption coefficient, α, the absorption index, K, and the optical energy gap Eopt, were found to be radiation and dopant dependent. The results are discussed on the basis of the radiation induced degradiation of PVC. |
