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