Abstract

Polyvinyl Alcohol - potassium iodide composite films have been prepared by using casting technique with different dopant concentrations of (2, 4, 6, 8, and 10) wt%. Some optical parameters of all films were studied. The UV-Vis spectra have been recorded in the range of (250-1100) nm. The results show that the filler content has significant effect on the transmittance, absorbance and other optical parameters of all samples. Furthermore, the results also show that the pure and PVA-KI have allowed indirect energy gap (Eg).
