本論文是使用受挫式內部全反射法並利用Kretschmann組態激發表面電漿波。使用不同材質金屬和不同厚度金屬來偵測漂白粉表面電漿波共振角變化。 光源波長、稜鏡材質、不同金屬、金屬薄膜層厚度都會影響表面電漿波共振角與反射率強度的變化。本研究使用光源(632.8nm)、稜鏡材質(磷化鎵),以金屬薄膜層厚度以及金屬材質為變因,用電腦進行模擬,找出激發表面電漿波之最佳金屬薄膜層厚度。
This paper is using the frustrated total internal reflection method and Kretschmann configuration to excite surface plasma wave. Using different materials and different thicknesses of metal to detect bleach surface plasma wave resonance angle. Light wavelength, the prism material, different metals, metal thin film layer thickness will affect the surface plasma wave resonance reflectivity and intensity .This study use light source (632.8nm), prism material (GaP), different materials and different thicknesses of metal on computer simulations. To find the best metal surface plasmon excitation wave film thickness. This paper bleaching powder in gold (Au) 50nm thickness and the silver (Ag) 50nm thickness are the best optimized resonance angle of surface plasma wave of Kretschmann configuration.
