Abstract

An optical waveguide (OWG) sensor for the detection of BTX gases is reported. The highly sensitive element of this sensor was made by coating the copper Nafion film over a single-mode potassium ion exchanged glass OWG. We used the OWG sensor to detect toluene gas as a typical example BTX gas. The sensor exhibits a linear response to toluene in the range of 0.25-4250 ppm with response and recovery times less than 25 s. The sensor has a short response time, high sensitivity, and good reversibility.

摘要

报道了一种用于检测BTX气体的光波导（OWG）传感器。该传感器的高灵敏度元件是通过在单模钾离子交换玻璃光波导上涂覆铜-纳夫ion膜制成的。我们以甲苯气体作为典型的BTX气体，使用该光波导传感器进行检测。该传感器在0.25-4250 ppm范围内对甲苯呈现线性响应，响应和恢复时间均小于25秒。该传感器具有响应时间短、灵敏度高和可逆性好的特点。
