| Summary: | 博士 === 國防大學中正理工學院 === 國防科學研究所 === 92 === Along with economic development and society industrialized, the by-products generated by the high technology — the environment pollution had caused ecological damage and detrimentally affected human health. How to fast detect the damage factors is an important research topic today. From a pratical point of view, the air and water pollution detections are most important and urgent damage factors. The key point of these detections is to develop high-sensitive, fast, cheap and free from the electromagnetic interference detectors. The surface plasmon resonance sensor (SPRS) is a sensitive method based on detecting the dielectric constant change on interface. The main target of the thesis was to implement a sensitive surface plasmon resonance chemical sensor. He-Ne laser was used as the light source and prism as the coupler for efficiently exciting surface plasmon resonance between the interface of metal film and detected samples. The study began from the research of the surface plasmon resonant theory and mechanism by analyzing the surface plasmon resonance exciting configurations, finding out the optimum parameters of the configuration, and designing a sensitive surface plasmon resonance chemical sensor. Then apply the SPRS on the chemical solutions and the harmful gases detections. In the chemical solution detection, the nanoparticle detections are exampled, and the harmful gas detections are focused on the hydrogen sulfide and solvent vapors detection. Based on the results of the thesis, the SPRS can be adapted to other harmful material detections in the future, and improve the industry environment and the personnel safety.
