本論文是利用受挫式內部全反射法和激發表面電漿波Kretshmann組態研究不同濃度的碘之表面電漿波共振角。 設計實驗架構是利用雷射光對Krestchmann組態激發表面電漿波及使用旋轉平台對Krestchmann組態作不同的角度的旋轉,再利用光功率計偵測不同反射光的強度,將所偵測實驗光信號送入電腦,進行分析研究,進而得到不同濃度之碘所產生的表面電漿波共振角度。 本次研究的Kretshmann組態結構:第一層介質為稜鏡,第二層介質為金屬,第三層的空氣改為碘水溶液。
This research project is using the excitations of surface plasma waves by the method of frustrated total internal reflection and Kretshmann configuration, different concentrations iodine of resonance angle. Experimental design light path of the laser light as the excitation of the surface plasma wave of the incident light source, use rotating platform and Krestchmann configuration, and then use of the power meter to detect the intensity of light under different incident angles, the detected the experimental optical signal into the computer, analysis and study, then get different concentrations of iodine surface plasma resonance angle. This research is to use the Kretshmann configuration (prism- metal- iodine solution).
