摘要

对高性能光纤相对湿度传感器（FO-RHS）的需求与日俱增。因此，利用液态脉冲激光烧蚀法制备了玫瑰孟加拉染料（RBD）功能化的椭圆形银纳米粒子（AgNPs），并将其用作传感涂层元件来设计基于光纤的湿度传感器。这些 NPs 表现出明显的表面等离子体共振吸收和荧光，且衰减寿命短。表面富含 OH 和 COOH 基团的 AgNPs 能有效吸附 H2O、解离 O2 和接受电子。针对聚乙烯醇测试了这些 FO-RHS 的湿度传感能力，结果表明它们具有出色的灵敏度（0.16 dB/%RH）和线性度（0.955 dB/%RH）。拟议的 FO-RHS 可能有利于实际应用。

Humidity sensing characteristics of rose Bengal dye-functionalized plasmonic silver Nanoparticles-coated Novel Fiber-Optic sensors

Demand of high performance fiber-optic relative humidity sensors (FO-RHS) is ever-growing. Thus, rose Bengal dye (RBD)-functionalized ellipsoidal silver nanoparticles (AgNPs) were made using pulse laser ablation in liquid method and used as sensing coating elements to design optical fiber-based humidity sensors. These NPs showed prominent surface plasmon resonance absorption and fluorescence with short decay lifetime. AgNPs surface enriched of OH and COOH groups enabled an efficient H₂O adsorption, O₂ dissociation, and electrons acceptance. Humidity sensing capacity of these FO-RHS was tested against polyvinyl alcohol, revealing excellent sensitivity (0.16 dB/%RH) and linearity (0.955 dB/%RH). Proposed FO-RHS may be beneficial for practical applications.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
