Recent strides in fiber-optic sensor (FOS) technology have expanded its utility across diverse fields, measuring an array of properties from chemical changes to light intensity. Fiber optic pH sensors stand out for their compactness and remote sensing capabilities. Plasmonic nanoparticles, specifically silver and gold, exhibiting localized surface plasmon resonance (LSPR), hold promise for pH monitoring, as their optical properties respond to factors like refractive index and pH. Our study contributes to this landscape by developing a pH sensor utilizing an Ag-PVA nanocomposite on U-bent fibers, with a comparative analysis against bulk Ag/PVA-coated fibers. This work aligns with the broader trend of advancing pH sensing technologies through innovative materials and methodologies, providing insights for enhanced performance in various applications.
