Abstract
The experimental temperature-dependent absorption, phogtoluminescence and photoluminescence excitation spectra of poly(p-phenylenevinylene) (PPV) are presented and a molecular theory is used to analyze the resu lts. In order to model the complicated system such as PPV, the structu ral inhomogeneity has to be included. The structural inhomogeneity is represented by the different Huang-Rhys factors associated with differ ent chain lengths. The theoretical spectra agree qualitatively with th e experimental results.
