摘要

本論文主要是在探討偶氮染料吸附在MOFs的表面增強拉曼散射的效應。以不同的入射光波長(488 nm、514.5 nm、632.8 nm)量測，發現在波長632.8 nm的光源有最大的增強效應。不同種類的MOFs會有不同的結構特性，使偶氮染料分子在MOFs上的吸附位向也不一樣。MOFs經由高溫處理後，從XRD和SEM圖譜分析，得出MOFs會崩解形成金屬氧化物，也證明MOFs之SERS來源是源自於金屬氧化物。從XPS圖譜分析，看到圖譜上金屬氧化物中的峰位位移得知染料分子與MOFs的金屬氧化物團簇有電荷轉移作用。針對XRD、SEM、XPS與拉曼光譜的關聯性，我們會有更詳盡的討論。

This thesis investigates surface-enhanced Raman scattering (SERS) effects by adsorbing azo dye upon MOFs. Using various incident light wavelengths (488 nm, 514.5 nm, 632.8 nm), the maximum enhancement effect was observed at 632.8 nm. Different types of MOFs showed different structural characteristics and adsorption sites of azo dye molecules. After high-temperature plasma processing, the XRD and SEM analyses showed that MOFs decomposed into metal oxide. This suggests that the SERSs of MOFs are indeed due to metal oxides.The shifts in the metal oxide peaks in the XPS spectra indicate the charge transfer interaction between the dye molecules and the metal oxide clusters of MOFs. This thesis will also include a detailed discussion of the XRD, SEM, XPS and Raman analyses.
