Abstract
A silicon-based surface plasmon resonance (SPR) technique has been successfully applied to NO2 sensing at ppm level using devices with uncoated and phthalocyanine-coated gold films. Surface-enhanced Raman scattering (SERS) has been used as an additional data-acquisition channel capable of providing spectroscopic selectivity and amplified sensitivity. Reversible responses of both SERS and SPR-induced photosignals produced by Au-on-Si grating structures coated with thin 18-crown-6 H(2)pc phthalocyanine films are simultaneously recorded for exposures of the films to 10 ppm of NO2 in air. Possible sensing applications are discussed.
