Abstract

Effects of low-intensity UV treatment on the OPTICAL CONSTANTS of red BS dye-doped polymethyl methacrylate (PMMA) film including refractive index, extinction coefficient, real and imaginary parts of dielectric constant, BAND GAP ENERGY, URBACH ENERGY, and refractive index dispersion parameters are measured and calculated.Changes in OPTICAL CONSTANTS mainly occurred in the UV–VIS range. Red BS dye, which is used as a UV absorber impurity in PMMA films, generated another energy band gap which was increased by UV treatment. Although some of the OPTICAL CONSTANTS of PMMA are not changed noticeably by the treatment in this low range of UV radiation, our results confirm that polymeric changes such as chain scission and depolymerization can directly affect the OPTICAL CONSTANTS of PMMA.
