Synchronous Fluorescence Spectroscopic Technique for the Simultaneous and Rapid Determination of Polycyclic Aromatic Hydrocarbons in Vegetable Oils and the Preliminary Study of Its Coupling with Surface Plasmon-Coupled Emission

Abstract

同步荧光技术（synchronousfluorescencespectrometry，SFS）是一种基于激发、发射波长仪彼此间保持一定的关系进行同时扫描而获得荧光光谱的一种荧光分析技术。因其具有简化光谱、减少光散射、提高选择性和灵敏度等优势，已逐渐发展成为多组分体系快速检测的有力工具。表面等离子体耦合发射荧光（surfaceplasmon-coupledemission，SPCE）是利用金属近场作用范围内的受激分子与金属表面等离子体之间的耦合作用而建立起来的一种新型的界面增强技术。凭借其定向发射性、偏振性、波长分辨性、能排除远场背景信号干扰等优势，SPCE检测方法的研究和应用得到了迅猛发展。本...Synchronous fluorescence spectrometry (SFS) is a fluorescence analysis technique based on the definite relation between the excitation and emission wavelengths in the process of simultaneous scanning to obtain the fluorescence spectrum. Owing to its advantages of simplified spectrum, less light scattering, high selective, and sensitive, SFS has been gradually developed to a powerful tool for the r...学位：理学硕士院系专业：化学化工学院_分析化学学号：2052013115156
