研究目的
Investigating the surface plasmon properties of multi-tip gold nanostars (GNSs) and their resonance peaks dependency on size, spacing, quantity, and refractive index.
研究成果
The simulation results demonstrate that multi-tip GNSs exhibit stronger resonance intensity and local field enhancement compared to traditional spherical and triangular nanostructures. The resonance peaks can be regulated by adjusting the GNSs' size, distance, quantity, and surrounding refractive index, offering potential applications in surface-enhanced Raman scattering and fluorescence.
研究不足
The study is theoretical and relies on simulations, which may not fully capture all real-world physical interactions and material behaviors.
