Characterization and Optical properties of Lead doped Poly Vinyl Alcohol Films

Abstract

Pure and Lead-doped poly vinyl alcohol (Pb-PVA) films were prepared by volume mixture using casting technique by different concentrations (2% and 6%). The characteristics of composites was investigated by FTIR spectroscopy. The optical properties, absorption and transmission of films were investigated through the transmission measurements at room temperature in wavelength range of (200-1100 nm). Overall we observe that the values of Eg decreases by the increasing of concentration Values of Eg determined to be 6.2, 4.745 and 4.75 eV for pure PVC, 2% and 6% Pb respectively.
