摘　　要：We investigate the re-exciting process of a soliton, a polaron and a bipolaron in conjugated polymers. For a soliton case, the processes S^0 ＋ hv→ S^± P↓± and S^± ＋ hv→S^0 ＋P± will take place, where S^0 ,S^± and p^± express a neutral soliton, charged solitons and charged polarons, respectively. For a polaron case, the processes P^± ＋ hv→ p^↓± ＋ Bp^±2 will occur, where BP^±2 expresses a charged bipolaron with two electronic units. For a bipolaron case, the processes BP^±2 ＋ hv→ P^± ＋ P^± and BP^±2 ＋ hv→ BP^＋2 ＋ E0 are obtained.We investigate the re-exciting process of a soliton, a polaron and a bipolaron in conjugated polymers.
