本研究的目的在於探討金相關奈米材料、與其在經過表面修飾後的性質，共分為兩部分。在第一部分中，我們利用在近紅外光具有表面電漿共振吸收的金銅合金奈米粒子，討論其在表面修飾硫化銅後，在近紅外光雷射照射下，金銅合金與硫化銅間的表面電漿共振能量轉移，對於光熱轉換效率的影響；而在第二部分中，由於目前普遍合成金奈米殼的方法所需時間長且步驟繁複，因此本研究提出一改良後的方法，能在較短的時間內合成金奈米殼，且在實驗前處理及步驟上都較為便捷，進而能提升合成上的效率。

The purpose of this study is to explore the gold-related nanomaterials’ surface coating and characterizations. There had two parts in this study. In the first part of our research, we synthesized gold-copper alloy nanoparticles which had a LSPR absorption in NIR region and then coated copper sulfide layer on the gold-copper alloy nanoparticle to explore whether the LSPR energy transfer between the two materials could enhance photothermal conversion efficiency. In the second part, we proposed an improved method to synthesize gold nanoshell which took less time and had easier procedure compared to the common methods. We also demonstrated that our method could be used to form different size and shell-thickness gold nanoshell.
