摘要：

Eriochrome Black T doped polyvinyl alcohol film was prepared on a glass substrate via the casting method. Optical microscope image of the film was taken by an optical microscope and analyzed by an Image J and origin 2008 software where it was proved that the film was free of defects and holes and uniformly distributed over entire area of the substrate. The optical constants of the film were calculated via the optical absorbance and transmittance in the wavelength range 350-900 nm via the use of a set of known mathematical formulas together with Wemple and DiDomenico model. The optical conductivity and the electrical conductivity of the prepared film in response to external electric filed are obtained using two more equations where it was found that the prepared film have high optical conductivity of the order of 10(12)s(-1)and an electrical conductivity of the order of 10(4)(S cm(-1)).
