The performance of the surface plasmon resonance (SPR) sensors using gold (Au)-coated arc-shaped fiber and titanium carbide (Ti₂C) MXene deposited on the Au-coated arc-shaped fiber was investigated using different concentrations of lead ions (Pb²⁺). The sensitivity of the Ti₂C deposited Au-coated arc-shaped fiber SPR sensor was 14.81 nm/M, about 1.3 times better than that of Au coating alone. The Ti₂C deposited Au-coated arc-shaped fiber SPR sensor's performance has a detection limit (LOD) of 0.241 M, detection accuracy (DA) of 6.58 × 10^-3 nm⁻¹, the figure of merit (FOM) of 0.097 M⁻¹, and a sensor resolution of 0.101 M. The large surface area of MXene enhances surface contact, and the formation of functional groups (–OH, =O, -F) on the MXene surfaces promotes hydrophilic properties, facilitating the trapping of water molecules. This work provides a foundation for experimental exploration into integrating other MXene materials with optical fiber SPR sensing devices.

使用不同浓度的铅离子研究了使用金（Au）涂层弧形光纤和沉积在金涂层弧形光纤上的碳化钛（Ti ₂ C）MXene的表面等离子体共振（SPR）传感器的性能（铅²⁺ )。_{Ti 2} C沉积镀金弧形光纤SPR传感器的灵敏度为14.81 nm/M，比单独镀金的灵敏度提高了约1.3倍。Ti ₂ C沉积Au弧形光纤SPR传感器的检测限(LOD)为0.241 M，检测精度(DA)为6.58  ×  10 ^-3 nm ^-1，品质因数(FOM)为0.097 M ⁻¹，传感器分辨率为 0.101 M。MXene 的大表面积增强了表面接触，并且 MXene 表面上官能团（–OH、=O、-F）的形成促进了亲水性，有利于捕获水分子。这项工作为将其他 MXene 材料与光纤 SPR 传感装置集成的实验探索奠定了基础。
