Highly Sensitive Chemical Sensors by Functional Integration of Nanoporous Zeolites with Photonic Devices
Abstract
Recently, we discovered that the nanoporous zeolite materials possess the unique combination of optical and chemical properties suitable for developing highly sensitive chemical sensors. This paper summarizes our recent work in developing such highly sensitive chemical sensors by functionally integrating zeolite thin films with optical fiber devices. These include the zeolite Fabry-Perot interferometric sensor and the zeolite thin film-coated thermal long period fiber grating sensor. Both types of sensors operate by monitoring the adsorption-induced optical refractive index changes in the zeolite thin film. The sensors were tested using various organic chemicals with different molecular sizes and in both vapor and liquid phases.
