| 摘 要： | 做为由单层碳原子紧密堆积而成的六边形蜂窝状二维晶体,石墨烯具有高载流子迁移率、良好的生物兼容性和优异的化学稳定性。本文简要综述了石墨烯-金属纳米粒子复合薄膜在表面增强拉曼散射研究进展,以及石墨烯等离激元的激发方式和传感性能。在可见光波段,石墨烯和金属纳米粒子之间的耦合使复合薄膜具有强的光学吸收和局域电场增强,从而使复合薄膜可以作为高灵敏的表面增强拉曼基底。在中红外波段,除可以利用石墨烯微纳结构激发等离激元,还可以对介电基底进行微纳加工利用波导模式激发,使得石墨烯等离激元可能用于折射率传感。讨论了石墨烯基复合薄膜研究过程中面临的机遇和挑战,展望了其在表面增强拉曼和传感方面的应用前景。 |

| Abstract: | The graphene, a single layer of carbon atoms in a hexagonal configuration, enjoys high carrier mobility, good biocompatibility and chemical stability. This paper briefly reviews the recent research progresses in the surface-enhanced Raman scattering (SERS) of graphene-metal nanoparticles (NPs) hybrid films, the excitation of graphene plasmons and the performance in sensing. In the visible region, the coupling between the graphene and the metal NPs allows the hybrid films to have enhanced absorption and much stronger electric field enhancement, and thus they can be used as highly sensitive SERS substrates. In the midinfrared region, the graphene plasmons can be excited by directly fabricating the graphene or fabricating the dielectric substrates with the help of guided-mode resonances, making them promising in refractive index sensing. In addition, the opportunities and challenges in this area are discussed. |
