Auxiliary film modulated SPR sensor for simultaneous refractive index and temperature sensing
A dual-channel surface plasmon resonance (SPR) optical fiber sensor for simultaneous refractive index (RI) and temperature sensing is proposed on the modulation effect of auxiliary films. Magnesium fluoride (MgF2) and titanium dioxide (TiO2) films sputtered onto the silver film induce a thickness-dependent redshift of...
