中文摘要 |
本論文主要探討金奈米棒的熱穩定性。金奈米棒會因為受熱而同時產生熔化與變形,金奈米棒的長寬比會影響其定域化表面電漿共振效應,所以在高溫下,金奈米棒的表面電漿共振吸收會發生改變。本論文採用單矽源、雙矽源在事先製備的金奈米棒表面包覆二氧化矽增強其熱穩定性;再透過水熱法進一步穩定外層二氧化矽結構,最後經由高溫爐進行高溫燒結,測試其熱穩定性,透過上述處理,可以很明顯地避免金奈米棒在高溫變形,使金奈米棒在熱穩定性被改善後,可以應用在輔助改善染料敏化太陽能電池光電轉換效率。 |
英文摘要 |
Thermal stability of gold nanorods (AuNRs) is mainly investigated in the thesis. Both the melting and deformation of AuNRs were observed at high temperatures. Localized surface plasmon resonance (LSPR) of AuNRs is determined by the aspect ratio of AuNRs. LSPR absorption will be changed at high temperatures. The surface of the prepared AuNRs is coated with silica by adding one or two silicon reagents. And the structure of outer silica was further stabilized by the hydrothermal method. Silica-coated AuNRs are calcined by high-temperature furnace to test their stability. The melting and deformation of AuNRs can be significantly prevented by the above treatments. Therefore, silica-coated AuNRs with the enhanced thermal stability could be usefully applied in improving photoelectric conversion efficiency of dye-sensitized solar cell. |
