A detailed primeval study on the lossy mode resonance (LMR) behavior of zinc oxide (ZnO)-coated optical fiber as a refractive index sensor is carried out. Theoretical evaluation predicts ZnO as a good choice for the LMR-based chemical and gas sensor operating in the visible region of the electromagnetic spectrum. To confirm, the optical fiber probe has been fabricated with an optimized film thickness of ZnO over an unclad core of fiber and characterized. Additionally, an LMR-based nanosensor platform utilizing ZnO has also been investigated to find the compatibility of a nanotechnological LMR sensor. The nanostructured LMR sensors have shown enhanced sensitivity in comparison to a bulk layered probe.
对涂覆氧化锌(ZnO)的光纤作为折射率传感器的损耗模式共振(LMR)行为进行了详细的原始研究。理论评估预测,ZnO是在电磁光谱可见光区域工作的基于LMR的化学和气体传感器的理想选择。为了进行验证,已在未包层的光纤纤芯上制备了具有优化ZnO膜厚度的光纤探头并进行了表征。此外,还研究了一种利用ZnO的基于LMR的纳米传感器平台,以寻找纳米技术LMR传感器的兼容性。与块状分层探头相比,纳米结构的LMR传感器显示出更高的灵敏度。
