Absorption-detected magnetic-resonance studies of photoexcitations in conjugated-polymer/C60 composites |

Description |
Photoexcitations in poly[2-methoxy-5-(2'-ethyl-hexyloxy -p-phenylene vinylene] (MEH-PPV) and composites of MEH-PPV and C60 (MEH-PPV/C60) were studied by photoinduced absorption and absorptiondetected magnetic-resonance spectroscopies. We report direct evidence that the prominent triplet photoexcitations in pristine MEH-PPV are effectively quenched in MEH-PPV/C60 . In contrast, the dominant photoexcitations in MEH-PPV/C60 are spin-1/2 excitations: polarons on the polymer chains; and polarons on the C60 (C-60). |
