Abstract:

The optical properties of the undoped Poly(3-octylthiophene) (P3OT) – Poly(methyl methacrylate) (PMMA) polymer blend film and the Bromophenol blue (BPhB) dye – doped  P3OT – PMMA polymer blend films were studied. The undoped polymer film and the dye - doped polymer films at different dye concentrations were prepared using casting method. The optical absorbance and transmittance spectra were measured in the wavelength range 300 – 1100 nm for different dye concentrations using UV – Visible double – beam spectrophotometer. These optical spectra were used to characterize the optical properties of the prepared polymer films. The essential optical parameters of the BPhB dye – doped polymer blend film, such as, reflectance (R), absorption coefficient (α), extinction coefficient (k), refractive index (n), optical and electrical conductivities (σopt and σelect), and optical energy band gap (Eg), were determined. The effect of the dye concentration on these parameters was investigated. The results reveal the suitability of the BPhB dye – doped P3OT – PMMA polymer blend films for optical and photonic devices applications.
