| Outline of Final Research Achievements |
We developed a plasmonic sensor for surface-enhanced Raman spectroscopy (SERS) of the tribofilms; we investigated tribofilms generated from lubricant additives by X-ray photoelectron spectroscopy (XPS) and SERS with the plasmonic sensor, and compared the results. As a result, we found that the sensitivity of SERS performed with the plasmonic sensor is similar to that of XPS. Next, we tried to develop a plasmonic sensor for Fourier Transform Infrared Spectroscopy (FTIR). It was confirmed that the developed sensor was useful to increase the intensity of the FTIR signals. We also found that the Ag island film pattern affected the performance of plasmonic sensor. Then, we studied the optimization of the Ag island pattern in order to improve the performance, varying mainly the amount of Ag deposition. However, we could not achieve to obtain the sufficient improvement. It was suggested that we should develop the improved process of Ag film deposition with island pattern in the future.

| Academic Significance and Societal Importance of the Research Achievements |
これまで表面プラズモンの増強効果を利用したラマン分析の研究は行われているが、FTIR計測への応用はあまり知見されない。本研究はそのテーマに挑戦したものであり、この課題が解決されると、安価・簡便な方法で、種々の機械の相対運動する部分で省エネルギーの観点から大きな問題となる複雑なトライボロジー現象が分析可能となり、ナノトライボロジー分野が開拓される。その意味で学術的および社会的な意義は大きい。
