Effect of Thickness on The Optical Parameters of PVA:Ag

Abstract

Poly(vinyl alcohol) doped Ag films with different thicknesses were prepared by castingmethod. The thickness of the prepared films were 10, 20, 30,and 40 μm. Transmission andabsorption spectra have been recorded in order to study the effect of increasing thickness onsome optical constants such as transmittance, reflectance, absorption coefficient, refractiveindex, extinction coefficient, and real and imaginary parts of dielectric constant. This studyreveals that all these parameters affect by increasing the thickness.
