摘要

拉曼散射光譜已經被廣泛地使用到各個不同的科學領域，是現在做為探測分子結構及原子間交互作用力的一項利器。本文主要針對表面增益拉曼散射技術與針尖式增益拉曼散射技術之相關背景與設備做介紹。文中提出液態分子與固態薄膜兩種表面增益拉曼散射技術之應用實例。其一為結合奈米技術控制奈米粒子之顆粒大小與表面增益拉曼散射技術應用於水溶液稀薄染料分子之鑑定。其二為利用循環伏安法模式將其奈米拉子分散於導電高分子薄膜中，並將其薄膜控制在不同氧化還原電位，觀測其內部結構之變動。對於針尖式增益拉曼散射之應用而言，文中提出一石墨烯之實例，用以說明此技術之表面定位與分析功效。

Raman scattering technology is a powerful tool to identify molecule structures and atomic interactions and it has been widely applied in different fìelds. In this paper, we introduced the theories and instruments of surface enhanced Raman scattering (SERS) and tip enhanced Raman scattering (TERS) technologies. For the case of the SERS, we proposed two examples for the applications of surface enhanced Raman scattering including liquid molecules and so lid state thin films. One is the combination of nanotechnology and surface enhanced Raman scattering to evaluate the scattering intensity of dilute dye molecules in liquid solution by controlling the size of nanoparticles. The other is the identification of solid state conductor polymer films. We deposited the conductor polymer film and dispersed nanoparticles by cycle volumetric method. We further controlled the redox potential by potential stat to evaluate in the inner structure transformations. For the case of the TERS, we provided a case as to identify graphene structures to demonstrate the orientation function of the TERS.
