Ha. Mizes et Em. Conwell, PHOTOINDUCED CHARGE-TRANSFER IN POLY(P-PHENYLENE VINYLENE), Physical review. B, Condensed matter, 50(15), 1994, pp. 11243-11246
It has been suggested that excitation of poly(p-phenylene vinylene) (P
PV) by photons above the absorption edge produces principally polaron
pairs or split excitons. We show that such polaron pairs can account v
ery well for the peaks in the observed picosecond photoinduced absorpt
ion, the width of the absorption, and other phenomena associated with
photon absorption in PPV.
