Abstract: | 本研究以數值模擬的方法對位於奈米管內量子點的發光行為,以及其間福斯特能量共振轉移進行一系列的研究,由此展示奈米腔的效應。雖然這兩種行為與極化方向有強烈的相關性,但是量子點的整體發光及福斯特能量共振轉移效率都能夠增強。然後我們模擬將奈米管放在量子井附近時,量子井中的偶極子對奈米管中的量子點的福斯特能量共振轉移行為,我們發現奈米管的奈米腔效應能夠增強量子井與量子點間的福斯特能量共振轉移效率。下一步的研究中,我們於結構表面以及奈米管內加入銀奈米顆粒來產生表面電漿子耦合,我們發現表面電漿子耦合可以增強量子點或量子井的發光強度並增強量子井到量子點的福斯特能量共振轉移效率。最後,我的研究奈米管內的量子點供體到結構表面的量子點受體,及結構表面的量子點供體到奈米管內的量子點受體之交互福斯特能量共振轉移,結果顯示當量子點同時存在於表面及奈米管內時,整體的福斯特能量共振轉移效應顯得更強。 In this research, a series of numerical simulation study on the behaviors of quantum dot (QD) emission and Förster resonance energy transfer (FRET) between QDs in a subsurface nano-tube are performed to show the nanoscale-cavity effects. Although those behaviors are strongly polarization dependent, the overall efficiencies of QD emission and FRET can be enhanced through this effect. Then, with the nano-tube placed near a quantum well (QW), the FRET from a QW-dipole into a QD in the nano-tube is numerically studied. The nanoscale-cavity effect of the nano-tube can help in enhancing this FRET process. Next, an Ag nanoparticle (NP) is inserted into the nano-tube or placed on the top surface to induce SP coupling, which can enhance QD or QW emission and the FRET from the QW into QD. Finally, the behavior of cross-FRET is numerically studied to show that the FRET process from a QD donor in the nano-tube (on the top surface) into a QD acceptor on the top surface (in the nano-tube) makes an important contribution to the overall FRET effect when QDs exist in the subsurface nano-tube and on the top surface at the same time. |
