dc.description.abstract | 能量傳遞的機制一直是光電物理裡面重要的一個課題,尤其是對共軛導電高分子而言更是如此。導電高分子具有良好的光電特性,而這些特性都是具有研究及商業上的價值的。也因此,人們長久以來盡各種努力試圖揭開能量傳遞機制的秘密和其中的未知。在本論文中所討論的研究材料是短鏈的MEH-PPV分子。藉由時間解析單光子計數的技術,我們得以發現能量傳遞是有效的,我們也發現能量傳遞的方向是從較小的到較大的發光團。我們也對此短鏈的分子提出了一個簡單的模型。實驗結果與此模型有一致性。 | zh_TW |
dc.description.abstract | Energy transfer mechanism is a big topic on opto-electrophysics, especially in conjugated conducting polymers. The conducting polymer exhibits good optoelectric properties, which are worthy of research and commercial values. People, therefore, have done their efforts on studies to unveil the secrets and unknowns of the energy transfer mechanism. In this thesis, the short chain MEH-PPV polymer is studied. By using the time-correlated single photon counting technique for the time-resolved spectroscopic measurement and the spectrum shift study, we can find that the energy transfer is efficient and the direction is from smaller to larger chromophores. A simple polymer chain model for our short chain polymer is also proposed and found to be consistent with the experimental data. | en |
