Photonic Crystal Sensors for Detecting Vapors of Benzene, Toluene, and o-Xylene

详细

The effect benzene, toluene, and o-xylene vapors have on the optical properties of a photonic crystal sensor matrix and its components is studied by UV–visible diffuse reflectance spectroscopy. The effect the material of the photon assembly substrate has on the band gap parameters is considered. The possibility of visually detecting vapors of saturated nonpolar organic solvents using a photonic crystal–based sensor is demonstrated. A mechanism is proposed for the analytic response of the sensor.
