Design and optimization of the optical fiber surface plasmon resonance hydrogen sensor based on wavelength modulation

Optical fiber sensor based on surface plasmon resonance for rapid detection of avian influenza virus subtype H6: Initial studies

“…Optical-fiber-based SPR sensors have more advantages over conventional prism-based SPR sensors, particularly in terms of flexibility and cost . Currently, opticalfiber-based SPR sensors have been widely used in chemical sensors (Boehm et al, 2011) and gas sensors (Kim et al, 2005;Wang et al, 2013).…”

Introduction

“…76 The sensing structure consists of layers of silver, silica, tungsten oxide, and platinum over unclad core of the fiber. The sensing is based on the chemical reaction of hydrogen gas with tungsten and platinum resulting in the change in their dielectric constants.…”

Nanoplasmonic hydrogen sensing

“…These systems have also shown smaller hysteresis for the hydride formation/decomposition 66 . Apart from the Pd based sensors, hydrogen sensing layers consisting of ITO 67 or WO 3 /Pt composite films 68 have also been reported.…”
