摘要：

The spectrally resolved decay of photoluminescence in PPV - type conjugated polymers has been measured employing fluorescence-up-conversion and Streak-camera techniques. The results are in account with the concept of stochastic excitation transport amoung an energetically disordered manifold of chromophores, identified as subunits of the polymer chain comprising several repeat units. They demonstrate that the primary excitations are of excitonic origin.
