Abstract

A 4-parameter gas sensor that can simultaneously detect methane (CH₄), relative humidity (RH), hydrogen (H₂), and hydrogen sulfide (H₂S) is designed and analyzed. It uses a 4D-type coreless optical fiber as the substrate, gold (Au) as the plasmonic medium, and cryptophane-A/ultraviolet-cured fluorosiloxane complex (Crypt-A/UVCFS), polyvinyl alcohol (PVA), Pd-WO_3, and zinc oxide (ZnO) as the sensing materials. Simulation results show that in the ranges of methane concentrations (c(CH₄)) of 0%-2%, RH of 30%-70%, hydrogen concentration (c(H₂)) of 0%-2%, and hydrogen sulfide (c(H₂S)) concentration of 0–80 ppm, the average CH₄ sensitivity, RH sensitivity, H₂ sensitivity, and H₂S sensitivity are − 76 nm/%, -2.2 nm/%RH, -153 nm/%, and 15 nm/ppm, respectively.

基于表面等离子体共振（SPR）的四参数气体光纤传感器用于同时检测甲烷、相对湿度、氢气和硫化氢

设计并分析了一种能够同时检测甲烷（CH4）、相对湿度（RH）、氢气（H2）和硫化氢（H2S）的4参数气体传感器。它采用4d型无芯光纤为衬底，金（Au）为等离子体介质，隐烷- a /紫外固化氟硅氧烷络合物（Crypt-A/UVCFS）、聚乙烯醇（PVA）、Pd-WO3和氧化锌（ZnO）为传感材料。仿真结果表明，在甲烷浓度（c(CH4)）为0% ~ 2%、RH为30% ~ 70%、氢气浓度（c(H2)）为0% ~ 2%、硫化氢（c(H2S)）浓度为0 ~ 80ppm范围内，CH4、RH、H2和H2S的平均灵敏度分别为- 76 nm/%、-2.2 nm/%RH、-153 nm/%和15 nm/ppm。

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.
