摘要

这封信描述了一种利用局部表面等离子体共振（LSPR）的新型光纤相对湿度（RH）传感器的开发和特性。该传感器采用内部合成的氧化石墨烯-氧化锌纳米复合材料（NC）掺杂二氧化硅薄膜，涂覆在金纳米颗粒涂覆的u型弯曲塑料包层二氧化硅（PCS）光纤上。在15-90%的相对湿度范围内具有良好的线性响应，灵敏度为0.1359 nm/%RH，响应速度快，恢复时间为5s和7s。传感器的响应是完全可逆和可重复的。

LSPR-Based Optical Fiber Sensor Utilizing GO-ZnO Nanocomposite for Relative Humidity Measurement

This letter describes the development and characterization of a novel optical fiber relative humidity (RH) sensor leveraging Localized Surface Plasmon Resonance (LSPR). The sensor utilizes an in-house synthesized GO-ZnO nanocomposite (NC)-doped silica film coated on gold nanoparticle coated U-bend plastic-clad silica (PCS) fiber. It shows a linear response across a broad RH range of 15-90%, with a sensitivity of 0.1359 nm/%RH, and features rapid response and recovery times of 5s and 7s. The sensor’s response is fully reversible and repeatable.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
