Abstract
In this research, samples of pure poly vinyl alcohol and poly vinyl alcohol doped with silver carbonate were prepared using casting technique. The PVA samples with AgCO3 additive prepared with different percentages(0,1,2,4 and 5) wt.% and different thickness. The experimental results showed that the absorption coefficient increases and energy gap of the indirect allowed and forbidden decreases with increase the weight percentage of silver carbonate, the extinction coefficient increases with increase the silver carbonate content. The mechanical properties(Velocity of Ultrasonic wave, Specific Acoustic Impedance, Bulk Modulus and Compressibility change with increase the concentration of silver carbonate
