Localized-surface-plasmon-resonance-based optical fiber mercury ion sensor employing CNT/PVA nanocomposite
A novel highly sensitive and selective LSPR based U-shaped optical fiber mercury ion sensor is developed. The sensor employs carbon nanotubes and polyvinyl alcohol (CNT/PVA) nanocomposite as the sensing material. Proposed sensor exhibits a remarkably low detection limit of 0.08 ppb, high sensitivity of 0.2458 nm/ppb, linear response within the range of 0–30 ppb, offering an accurate and cost-effective solution for monitoring water quality.
