摘要

本文报道了基于导纳轨迹法设计基于表面等离子体共振(SPR)传感器的数值模拟研究，该传感器采用硫化物和其他常用玻璃。在衰减全内反射(ATIR)模式下，利用导纳轨迹法研究了由玻璃棱镜、金(Au)金属薄膜和水(传感层)组成的简单的Kretschmann-Raether棱镜多层结构。硫系材料具有高折射率的红外传输特性，为传感应用提供了一定的优势。通过与其他常用玻璃的导纳轨迹图和共振曲线的比较，研究了硫系玻璃在近红外(NIR)波段对SPR传感的影响。

Influence of chalcogenide glass on surface plasmon resonance based sensor design in near infrared region using admittance loci method

A numerical simulation study based on the use of admittance loci method in design of surface plasmon resonance (SPR) based sensor using chalcogenide and other commonly used glasses has been reported in this paper. A simple Kretschmann-Raether prism-based multilayer structure consisting of a glass prism, Gold (Au) metal film and water (sensing layer) has been investigated with the use of admittance loci method in Attenuated Total Internal Reflection (ATIR) mode. Infrared transmission properties of chalcogenide material along with high refractive index offer certain advantages for sensing applications. Admittance loci plots as well as resonance curves using chalcogenide glass has been compared with those for other commonly used glasses in order to study their effect on SPR sensing in near infrared (NIR) wavelength region.
