摘要

金属涂层光栅结构表面等离子体的共振激发在各种光子器件应用中起着至关重要的作用。表面等离子体共振（SPR）在传感技术中有着广泛的应用。贵金属合金化提供了一种创新的方法来制造具有可调光学特性的材料。在这项研究中，我们研究了Ag-Cu合金纳米层压印在DVD和蓝光光盘的光栅结构上以激发表面等离子体激元的有效性。采用等离子体磁控溅射法制备了不同厚度的Ag0.95Cu0.05合金纳米层。结果表明，该合金具有较高的等离子体耦合效率。此外，对纳米结构光栅的光谱分析显示出窄带等离子体共振峰，特别是在蓝光光盘中，强调了其显著提高表面等离子体共振（SPR）传感器灵敏度的潜力。

Surface plasmon resonance of nanometer Ag-Cu alloy layers on Blu-ray and DVD disks

The resonant excitation of surface plasmons on metal-coated grating structures plays a crucial role in various photonic device applications. The prominence of surface plasmon resonance (SPR) is numerous, particularly in sensing technology. Alloying noble metals provide an innovative approach to creating materials with tunable optical properties. In this study, we investigated the effectiveness of imprinting Ag-Cu alloy nanolayers onto the grating structures of DVD and Blu-ray disks to excite surface plasmons. Using the plasma magnetron sputtering method, we deposited nanostructured layers of an Ag_0.95Cu_0.05 alloy with varying thicknesses. Our results indicated that the alloy achieved a high plasmon coupling efficiency. Furthermore, spectral analyses of the nanostructured grating revealed narrowband plasmon resonance peaks specifically in the Blu-ray disk, underscoring its potential to significantly enhance the sensitivity of surface plasmon resonance (SPR) based sensors.

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
