| dc.description.abstract | 在本論文中，我們將會運用奈米球鏡微影術製作C環（C-ring）狀的奈米洞陣列，接著蒸鍍金與二氧化鈦，經飄膜後置於名片洞（hole-mask）上成為free-standing的金屬薄膜。此結構的局域性表面電漿共振（LSPR）位於紅外光波段，藉由調整曝光與蒸鍍等參數，可應用於表面增強紅外光譜。 我們使用直徑2 μm的polystyrene奈米球，藉由奈米球的自組裝排列特性，使其在已塗佈光阻的矽基板上形成單層緊密排列。接著以奈米球作為凸透鏡，將紫外光匯聚於光阻層，經顯影後得到特定形狀的奈米洞陣列。藉由改變曝光的傾角，並搭配旋轉載台，可製作出不同大小、粗細的C環奈米結構。然後我們進一步使用斜向蒸鍍製程，在光阻層鍍上一層足夠厚的金，便於接下來的飄膜，最後再正向鍍上一層二氧化鈦。在飄膜的步驟中，藉由丙酮將光阻舉離後，金膜會飄起。我們用名片洞將金膜撈出，使其平整的置於名片洞上，得到free-standing的金屬薄膜。 我們接著用傅立葉轉換紅外線光譜儀（FTIR）測量金膜的光譜，觀察其局域性表面電漿共振發生的波段位置。此奈米結構主要有兩個共振模態，其中與X方向偏振電場共振之模態之一位於1500 – 1600 cm-1之間，涵蓋4-aminothiophenol (4-ATP) 之吸收光譜的三個特徵峰。我們將500 μM的4-ATP溶液滴在金膜上，加熱到60°C 加速溶劑的蒸發，待風乾後測量其穿透光譜。將此光譜扣除純金膜的穿透光譜，即可獲得在此範圍之訊號增強後的4-ATP吸收光譜。經由此技術，我們能以低成本製作出大面積具奈米洞陣列的金屬薄膜，且free-standing技術可減少基板對FTIR測量的影響。經由調整曝光及蒸鍍等參數，可以將此金屬薄膜用於多種不同分子的表面增強紅外光譜，加以應用於生物感測等領域。 | zh_TW |
