| Abstract | ||
| The present paper aims to modify the optical and Dielectric properties of (PVA- PEG) with add different concentrations from ( nano MgO). In this work ,the absorption and transmission spectrums have been recorded at the wavelength range (200-800)nm . The absorption coefficient and energy gap of the indirect allowed and forbidden transition, extinction coefficient, index coefficient, real and imaginary dielectric constant have been calculated. | ||
