摘要: A high refractive index sensitivity of Au@Cu2−xS core–shell nanorods working in the near-infrared is theoretically demonstrated. The our sensor reaches 1200 nm per Refractive Index Unit (RIU), which higher than that other metal–metal nanorods. reason new materials and structure lead to a unique sensing principle. It noteworthy (RI) more susceptible effects shell-thickness core-radius ratio aspect ratio. These results show excellent performance can be treated as tool detect minute variations for small amounts chemicals biomolecules.
