摘要：
We observed plasmon resonance peaks at two different wavelengths by combining the plasmon waves from aluminum (Al) and gold (Au) nanoparticles (NPs). We used electron-beam lithography along with angle metal evaporation techniques to deposit a metal particle plasmon layer with nanometer-scale separation. The coupled plasmon layer has two peaks at 525 nm and 650 nm, which are different from the constituent individual metal plasmon layers of Al and Au NPs with peaks at 500 nm and 700 nm respectively. The experimental findings agree with absorption data from COMSOL modeling results due to interaction of two nanoscale plasmon particles.
