摘要

提出了一种新的异质结构表面等离子体共振（SPR）传感器，用于各种分析物。该传感器对探测介质折射率的变化高度敏感。它是由银、PtSe2和石墨烯制成的。对石墨烯厚度、PtSe2厚度和Ag厚度的性能进行了研究。本文采用传递矩阵法（transfer matrix method， TMM）进行仿真研究，并使用Maple 18软件对结构进行仿真。对于厚度为50 nm的银、三层PtSe2和单层石墨烯，在CaF2棱镜、PtSe2棱镜和石墨烯棱镜上沉积的灵敏度达到了542.5°/RIU。

Performance of a Novel Surface Plasmon Resonance Nanostructure Based on PtSe2 and Graphene Thin Films

A novel heterostructure of surface plasmon resonance (SPR) sensors for various analytes has been proposed. The suggested sensor is highly sensitive to the changes in index of refraction detecting media. It is made of Ag, PtSe₂, and graphene. A study on the performance of graphene thickness, PtSe₂ thickness, and Ag thickness has been performed. It is a simulation-based study using the transfer matrix method (TMM) method, while Maple 18 Software has been used to simulate the structure. Maximum sensitivity of 542.5 deg/RIU have been achieved for Ag with a thickness of 50 nm deposited on CaF₂ prism, PtSe₂ with three layers, and graphene with a single layer.

期刊介绍： Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons. Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
