The study aimed to investigate the optical properties of thin films made of polyethylene oxide dispersed with dopants of a fixed amount of iodine (0.1 wt %). The films prepared by the casting method were optically investigated as a function of the iodine fillers. The study used a UV-visible spectrophotometer technique with a wavelength ranging from (200 to 800) nm and determined the absorption coefficient, refractive index, energy gap, extinction coefficient, optical conductivity, and dielectric constant in the UV-visible wavelength range. The results showed a noticeable change in these optical values with polyethylene oxide doped with 0.1 wt% iodine composites compared with the pure polyethylene oxide films. These measured values of polyethylene oxide doped with 0.1 wt% iodine depend on the wavelength of the incident ultraviolet light.
