| Abstract | ||
| In the present work ,the effect of addition Lithium Fluoride on some optical properties of polystyrene has been studied . For that purpose , many samples has been prepared by adding Lithium Fluoride on the polystyrene with different volume percentages from these salts with polymer and by different thickness .The absorption and transmission spectra has been recorded in the wavelength range (300-1100)nm . The absorption coefficient and energy gap of the indirect allowed and forbidden transition have been determined . | ||
