Abstract

Visualization of the distribution of various gases makes us possible to recognize environmental circumstances, e.g., localization of dangerous chemical sources or human body odorants in the case of disaster scene. Localized surface plasmon resonance (LSPR) can detect various gases with changes of surrounding dielectric constant, and can be used gas sensor with high response / recovery speed and high spatial resolution, i.e., 2 dimensional LSPR gas sensor gas work as a gas image sensor device. The gas image sensor detects the gas distribution occurred on the LSPR substrate by an ordinal image sensor. The general LSPR gas sensor, however, does not have a molecular selectivity, then the identification of gas species is difficult. To overcome such disadvantages, pixelated LSPR substrate based on Au/Ag core-shell structure is fabricated by photo-induced growth by mask-less exposure system using a commercial video projector.
