Abstract

Pure and doped polycarbonate (PC) films with various doping ratio of
coumarin dye were prepared by using casting method. The absorption and
transmission spectra for these films were measured using UV/VIS
spectrophotometer technique in order to assessment the type of transition
which was found to be indirect transition. The optical energy gap of
polycarbonate (PC) was (4.24eV) and coumarin dye was (4.08eV), after
doping PC polymer with coumarin dye the maximum energy gap is(4.26eV) in
volume ratio(4ml). Also, the results showed that absorption coefficient,
refractive index, extinction coefficient and real- imaginary part of conductivity
slightly affects by doping
