| 中文摘要 | 局域表面電漿共振(Localized Surface Plasmon Resonance, LSPR)效應是金屬奈米顆粒在受到光的激發時產生的特殊光學現象,是探討礦物著色機制的新研究領域。本文整合最新的相關研究,探討LSPR效應的原理及其在礦物著色中的應用,並採用時域有限差分法(Finite-Difference Time-Domain, FDTD)模擬金屬奈米顆粒的光學特性。同時,藉由高解析度穿透式電子顯微鏡(High-Resolution Transmission Electron Microscope, HR-TEM)和球差校正穿透式電子顯微鏡(Aberration-Corrected Transmission Electron Microscope, AC-TEM)等表徵方法,結合聚焦離子束(Focused Ion Beam, FIB)技術,分析奈米顆粒的微觀結構。從天然礦物角度,以俄勒岡日光石中銅奈米顆粒的形狀差異為例,闡述LSPR效應如何影響礦物色彩,並提供對天然礦物成色的新解釋。從人工合成角度,藉由精確控制金屬奈米顆粒的尺寸、形狀及周圍介電環境,實現特定光譜範圍內吸收與散射特性的精准調控。本研究將LSPR效應的相關檢測、模擬與再現技術引入,目的在於寄望未來能結合臺灣過往對於熱液礦床的研究,為礦物著色機制與成因開闢一個新視野。 |
| 英文摘要 | The Localized Surface Plasmon Resonance (LSPR) effect is a unique optical phenomenon triggered when metal nanoparticles are excited by light, marking a fresh avenue for exploring mineral coloration mechanisms. This study synthesizes the latest research to examine the principles behind the LSPR effect and its applications in mineral coloration. It employs the Finite-Difference Time-Domain (FDTD) method to simulate the optical properties of metal nanoparticles. Additionally, techniques such as High-Resolution Transmission Electron Microscopy (HR-TEM) and Aberration-Corrected Transmission Electron Microscopy (AC-TEM), paired with Focused Ion Beam (FIB) technology, are used to investigate the microstructure of these nanoparticles. From the perspective of natural minerals, this work takes the shape variations of copper nanoparticles in Oregon sunstone as a case study to illustrate how the LSPR effect influences mineral color, offering a novel interpretation of natural mineral pigmentation. From a synthetic standpoint, precise control over the size, shape, and surrounding dielectric environment of metal nanoparticles enables tailored manipulation of absorption and scattering properties within specific spectral ranges. By integrating LSPR-related detection, simulation, and reproduction techniques, this research aims to pave the way for future studies that link Taiwan's prior investigations of hydrothermal deposits with new insights into the mechanisms and origins of mineral coloration. |
