    abstract = {The optical properties of prepared ZnO/PVC composites with different concentration: 0, 2, 6,
9 wt.% of ZnO have been investigated. The optical spectra were obtained in the UV wavelength range
(400-800 nm) using a spectrophotometer. The absorption coefficient and the optical Energy gap (E<sub>opt</sub>) have been opt
obtained from indirect allowed electron transitions in k-space at room temperature. The tail widths of localized
states in the band gap (E) were evaluated using the Urbach-edges method. It was found that both E and E<sub>opt</sub> vary with the concentration of ZnO in the composite.}
