Dopping Effect on Optical Constant of Poly (Vinyl Chloride)

Thick films of poly(vinyl chloride)(PVC) PVC doped with Zn(etx)2 salt complex have been prepared by cast method with fixed thickness almost (120±5) Microns. Optical studies were carried out in the wavelengths region(200-900)nm based on absorption transmition measurement. Optical parameters such as absorption coefficient(α) ,refraction index(n) and extinction coefficient(K) were observed to be effected by adding the dopant.Electrical parameters such as real(ε) imaginary(έ) part of dielectric constant were also calculated part of dielectric constant were also calculated from the optical parameters using Maxwell equation.
