Abstract

Graphene, molybdenum disulfide (MoS\(_2\)), and zinc oxide (ZnO) are proposed here to enhance the evanescent field of an optical fiber surface plasmon resonance (SPR) sensor. Gold and silver are the plasmonic materials, and the fiber core material is made of polymethylmethacrylate (PMMA). A Fresnel equations-based analysis is used, and the obtained results pointed out higher values of sensitivity, figure of merit, and FWHM (full-width at half maximum) when compared to conventional SPR sensors. In despite of silver-only based SPR sensor has a better performance, oxidation occurs, and the sensor’s lifetime is reduced. The addition of graphene layers leads to sensitivity values \(50\%\) higher than the conventional sensor. On the other hand, the MoS\(_2\)-based sensor improves the interaction of the sensor with the bio-recognition molecules, which is attractive for biomedical applications. When ZnO was added to the silver-based sensor, a highest sensitivity, 4740.9 nm/RIU, was obtained. Graphene-based silver SPR exhibit the highest FOM values.

石墨烯、二硫化钼和氧化锌场增强型光纤SPR传感器

本文提出了石墨烯、二硫化钼（MoS\（_2\））和氧化锌（ZnO）来增强光纤表面等离子体共振（SPR）传感器的倏逝场。金和银是等离子体材料，并且纤维芯材料由聚甲基丙烯酸甲酯（PMMA）制成。使用基于菲涅耳方程的分析，所获得的结果指出，与传统SPR传感器相比，灵敏度、品质因数和FWHM（半最大全宽）的值更高。尽管仅基于银的SPR传感器具有更好的性能，但会发生氧化，并降低传感器的寿命。石墨烯层的添加导致灵敏度值比传统传感器高（50%）。另一方面，基于MoS（_2）的传感器改善了传感器与生物识别分子的相互作用，这对生物医学应用具有吸引力。当将ZnO添加到基于银的传感器中时，获得最高灵敏度4740.9nm/RIU。基于石墨烯的银SPR表现出最高的FOM值。

期刊介绍： Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons. Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
