我们报告了一种利用锥形光纤表面等离子共振 (SPR) 探针来分析气相和液相的新方法。该技术采用具有修改几何形状的光纤 SPR 探头来调谐 SPR 耦合波长-角度对。观察到的复合光谱包括与气体和液体活性区域中激发的表面等离激元相关的两个不同的 SPR 下降。该传感器能够通过同时监测两个传感表面的 SPR 耦合波长来分别检测气相和液相的折射率变化。 (c) 2005 年美国光学学会。
We report a new approach to analyze both vapor and liquid phases by utilizing a tapered fiber optic surface plasmon resonance (SPR) probe. This technique employs a fiber optic SPR probe with a modified geometry to tune the SPR coupling wavelength-angle pair. The observed composite spectrum included two distinct SPR dips associated with surface plasmons excited in the gas and liquid active regions. This sensor is able to detect refractive index changes in both vapor and liquid phases individually by simultaneous monitoring SPR coupling wavelengths from the two sensing surfaces.
