建立了基于单边全内反射照明的针尖光谱响应检测装置。这为揭示其光谱响应和共振带提供了一种实验方法，对研究其光学性质和场增强机理具有重要意义。检测了镀金和银的硅针尖的光谱响应。这些尖端，然后使用在尖端增强拉曼光谱（TERS）检测下532 nm的激发，以证明场增强的共振激发的效果。讨论了在TERS中，测量的光谱响应与针尖增强性能之间的对应关系。
Based on unilateral total internal reflection illumination, a tip spectral response detection setup is built. This provides an experimental method for revealing the spectral response and resonance band, which are significant in investigating optical properties and the field enhancing mechanism. The spectral responses of silicon tips coated with gold and silver are detected. These tips are then used in tip-enhanced Raman spectroscopy (TERS) detection under 532 nm excitation to demonstrate the effect of resonant excitation on field enhancement. The corresponding relationship between the measured spectral response and the tip’s enhancement performance in TERS is discussed.
