| 摘 要： | 用电子－晶格耦合的紧束缚模型和求解实时牛顿动力学方程的方法研究了Ｃ60受光激发后的动力学过程，得到了受光激发后Ｃ60分子的能量，键结构和电子状态的动态演化，结果表明光激发Ｃ60分子演化成环状双极化子激子。该计算结果与中性富勒烯材料的荧光实验所得出的结论一致。

| Abstract: | The dynamical process of optical-excited C60 is studied by using the tight-binding model of electron-lattice coupling and solving the real-time Newton dynamical equation. The dynamical evolutions of energy, bond structure and electron states are obtained. The theory shows that the moleule of optical excited C60 turns into a ring-bipolaron-exciton which is consistent with the self-trapped polaron exciton observed in the luminescence experiment of neutral C60. |
