Herein, a surface-sensitive sensor was reported as an optical waveguide (OWG) gas sensor. The sensor exhibited some advantages, including simple preparation and high sensitivity. Further, it could be operated at room temperature. TiO2 and ZnFe2O4 were employed as sensitive materials to prepare a sensor with a high response to styrene gas. The TiO2–ZnFe2O4 sol was prepared by doping ZnFe2O4 via the preparation of a TiO2 thin film, and the TiO2–ZnFe2O4 sol was fixed at the surface of the tin-doped glass waveguide by the dip-pulling method. Furthermore, the optimum conditions of the sensor were studied, and the sensors that were prepared under optimum conditions were employed to detect different concentrations of styrene gases. The results demonstrated that the sensor exhibited a high response to the determination of styrene and was reusable. Moreover, it could detect styrene across the concentration range from 1,000 ppm to 100 ppb at ambient temperature.

掺杂铁酸锌的氧化钛(IV)薄膜光波导改进了苯乙烯的测定

在本文中,报道了表面敏感传感器作为光波导(OWG)气体传感器。该传感器具有一些优点,包括制备简单和灵敏度高。此外,它可以在室温下操作。TiO 2和ZnFe 2 O 4被用作敏感材料,以制备对苯乙烯气体具有高响应的传感器。TiO 2 -ZnFe 2 O 4溶胶是通过掺杂TiO 2薄膜和TiO 2 -ZnFe 2 O 4掺杂ZnFe 2 O 4来制备的。通过浸入拉法将溶胶固定在掺锡玻璃波导的表面上。此外,研究了传感器的最佳条件,并采用在最佳条件下制备的传感器来检测不同浓度的苯乙烯气体。结果表明该传感器对苯乙烯的测定显示出高响应,并且可以重复使用。此外,它可以在环境温度下检测浓度范围从1,000 ppm到100 ppb的苯乙烯。
