概要
- 論文の詳細を見る
Multiple surface plasmon resonance (SPR) sensors were prepared on a waveguide, and vapor sensing was carried out. A BK-7 slide glass was used as a waveguide core, and three pairs of Ag films (50 nm)/polymer films with various thicknesses were prepared separately on the waveguide. White light was input from the substrate edge, and the spectrum of the output light was observed. Discrete SPR dips can be observed in the output light spectra by selecting the dielectric constant and the thickness of the polymer film, which govern the SPR condition. The sensors with poly(vinyl alcohol) as sensing material were prepared and the water vapor sorption properties were investigated. Furthermore, polyisoprene, poly(vinyl carbazole), poly(methyl methacrylate), and perfluorinated polymer were used as sensing materials, and the detection of various vapors was carried out.
