| 摘 要： | 将甲基绿-聚乙烯醇薄膜固定在钾离子(K )交换玻璃光波导表面,研制出一种光学硫化氢气体传感器.实验结果表明,本传感器对浓度在20×10-9 ～1.3×10-6范围内的硫化氢气体有良好的线性响应(R= 0.989 7)和快速响应(t0.9小于3 s).本传感器具有灵敏度高、可逆性好、重现性高、成本低,结构简单和易制作等特点.

| Abstract: | An optical hydrogen sulfide sensor was fabricated by coating the methyl green -polyvinyl alcohol (PVA) film over a potassium ion (K+) exchanged glass optical waveguide (OWG). The results show that the sensor has good liner response to hydrogen sulfide gas in the range of 20×10-9 to 1.3×10-6 (R= 0.9897) with rapid response (t0.9 is less than 3s). The sensor was also characterized by high sensitive, good reversibility, high reproducibility, low cost, simple structure and easy fabrication |
