| 中文摘要 | 本研究開發多氧化物殼層包覆之奈米銀線，該技術不需使用模板、接種與表面活性劑。奈米銀線在成長同時表面形成一極薄(~1nm)TiO2殼層，導致其表面電漿共振往低能量（高波長）端偏移。極薄TiO2內殼層有利於進一步包覆TiO2 或CeO2外殼層，表面電漿共振持續往低能量偏移。藉由表面氧化物厚度、層數與折射率的設計與選用，本研究實現一維奈米結構表面電漿共振波長之可調控性。 |
| 英文摘要 | Without using templates, seeds and surfactants, this study successfully prepared multi-oxide-layer coated Ag nanowires that enable tunable surface plasmon resonance without size or shape changes. A spontaneously grown ultra-thin titania layer onto the Ag nanowire surface causes a shift in surface plasmon resonance toward low energy (high wavelength) and also acts as a preferential site for the subsequent deposition of various oxides, e.g. TiO2 and CeO2. The difference in refractive indices results in further plasmonic resonance shift. This verifies that the surface plasma resonance wavelength of one-dimensional nanostructures can be adjusted using refractive indices and shell oxide thickness design. |
