| dc.description.abstract | 在本論文中，我們研究了半導體量子點與奈米金屬柱的柵狀結構結合後所展現的物理特性。利用聚二甲基矽氧烷和DVD光碟片，我們成功的製作二氧化矽包著的金奈米柱的柵狀結構。同時結合了不同發光特性的硒化鎘量子點、碲化鎘量子點，我們發現個別量子點的螢光在激發光不同偏振下分別被增強。這種現象可以被解釋為不同發光特性的量子點分別耦合到排列整齊一致之金屬奈米柱柵狀結構的垂直表面電漿共振模態與平行表面電漿共振模態。隨著激發光的不同偏振，不同的表面電漿共振模態被激發並且增強不同的量子點發光。這樣的結果提供了一個選擇去製造智能的顏色可調發光元件。 | zh_TW |
| dc.description.abstract | In this thesis, we have reported the novel physical phenomena based on the composites of semiconductors quantum dots (QDs) and metallic nanorods grating. Taking advantage of polydimethylsiloxane (PDMS) and digital versatile disc (DVD), the silica-coated gold nanorods grating is fabricated. Combining with different QDs, it is found that the emission spectra of QDs can be enhanced selectively. The underlying mechanism is attributed to the fact that optical transitions of different QDs will couple with transverse or longitudinal surface plasmon (SP) resonance mode of well-aligned gold nanorods grating. Excitation with different polarizations will excite different SP resonance mode, which then enhances the emission of different QDs. The result shown here therefore provides an excellent possibility to create smart light emitting devices with tunable color. | en |
