Infrared-Sensor Based on Selenide Waveguide Devoted to Water Pollution
Abstract
The development of middle-infrared (MIR) sensors for organic pollutants monitoring in the aquatic environment is currently a challenge of great importance. The mid-infrared sensor based on evanescent wave spectroscopy is a promising analytical tool for simultaneous detection and quantification of a variety of pollutants such as hydrocarbon compounds. Chalcogenide glasses are particularly well adapted for sensing applications due to their wide domain of transparency (up to 10 – 16 μm depending on their composition). The aims of this study are to synthetize chalcogenide thin films for developing mid-infrared optical integrated platforms and perform their functionalization with polymers in order to increase the sensor sensitivity. Among (GeSe 2 ) 100−x (Sb 2 Se 3 ) x glass compositions, two selenide glass targets were chosen for their optical and physical properties. Thanks to attenuated total reflection spectroscopy, measurements were performed in water to detect aromatic hydrocarbons (benzene, toluene and the three xylene isomers) in the concentrations range of 25 ppb to 10 ppm. Detection measurements have also been fulfilled using seawater and ground-water. To increase their sensitivity, the use of metallic nanoparticles is one of the promising solutions based on Surface Enhanced Infrared Absorption (SEIRA). Thus, hybrid structures combining gold nanoparticles/chalcogenide glass and waveguides were fabricated and characterized.
