| Abstract | ||
| In the present work ,the effect of addition nickel on some optical properties of poly-vinyl alcohol has been studied . For that purpose , many samples has been prepared by adding nickel on the poly-vinyl alcohol with different weight percentages from nickel with polymer and by different thickness .The absorption and transmission spectra has been recorded in the wavelength range (300-900)nm . The absorption coefficient, extinction coefficient and energy gap of the indirect allowed and forbidden transition have been determined | ||
