Abstract
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.
