研究目的
To review progress in surface plasmon resonance (SPR) of two-dimensional (2D) and three-dimensional (3D) chip-based nanostructure array patterns, focusing on fabrication techniques, optical properties, and applications in sensing.
研究成果
The review concludes that plasmonic nano-arrays offer significant potential for applications in sensors, photovoltaics, and optoelectronics due to their tunable optical properties. However, it emphasizes the need for further development in fabrication techniques to overcome current limitations and for a 'device-by-design' approach to fully utilize plasmonic effects in practical applications.
研究不足
The review highlights challenges in fabricating large-area, long-range-ordered periodic nano-array patterns and the technical barriers in integrating plasmonic nano-arrays with semiconductor materials for practical applications. It also notes the limitations of current fabrication techniques in achieving high-throughput, low-cost production with excellent repeatability and controllability.
