ABSTRACT: The optical properties
of the pure polymer film and polymer films doped with Phenol Red dye at different
concentrations were investigated. The films were prepared using the casting
technique. Poly (methyl-methacrylate) (PMMA) polymer was doped with the Phenol
Red dye dissolved in a mixture of chloroform and little quantity of methanol,
used as suitable solvent for both the dye and the polymer. The spectral
absorption measurements of these films were carried out at different dye
concentrations using UV-Vis double-beam spectrophotometer in the wavelength
range 300 - 800 nm. The optical parameters of the prepared Phenol Red dye doped
polymer films, absorption coefficient (α),
extinction coefficient (κ),
refractive index (n), optical and
electrical conductivities (σopt and σelect), and optical
energy band gap (Eg), were
determined. The results showed that the Phenol Red dye doped polymer film is a
good candidate for photonic applications such as, solar cells, optical sensors,
and other photonic devices.
