Abstract:	本論文利用彩色CCD影像判斷奈米結構環境下的光譜變化，而在此論文中使用的檢測方式為改變環境折射係數，並以彩色CCD影像分析其光譜飄移現象。使用的奈米結構為奈米金粒子所構成的球形雙子及單顆球形粒子，於模擬中推估其隨環境折射係數變化所造成的光譜波峰飄移量。在實驗中將不同的折射率匹配液滴於樣品表面，以彩色CCD擷取包含奈米結構之影像進行分析，並以光譜儀測量奈米結構之光譜做為驗證。;In this study, the spectrum shift due to nano-environmental variation is determined by color CCD images. To mimic this, index matching fluid with different refractive indices were drop coated on isolated Au nano spheres in forms of monomer and dimers. The scattered image was then recorded by color CCD and the sRGB values were converted to CIE 1931 color space. The color difference in response to the corresponding index difference was compared to that obtained by spectrometer.
