Abstract :
In this work, we present a characterization study of the electronic and vibrational properties of regioregular poly(3-decylthiophene) by means of luminescence, optical absorption and Resonant Raman Scattering (RRS) measurements. Photoluminescence studies carried out with an excitation wavelength of 2.42 eV (514.5 nm) show a luminescence signal characterized by a structured band with a maximum at 2.66 eV. Results obtained by RRS are presented and discussed. By using a dynamical model based on a valence force field, Raman vibrational modes are assigned and a set, of force constants is determined for the polymer
