根据PVK掺杂后荧光谱的改变,提出了PVK掺杂的掺杂机制,沿PPV链是极化子和双极化子态,而链间是由于双极化子的跃迁。实践结果与模型相符。
According to the change of fluorescence spectrum after PVK doping, the doping mechanism of PVK doping is proposed. The doping PPV chain is the polaron and the bipolar state, while the interchain is due to the bipolar transition. The result of practice is consistent with the model.
