Abstract

We observed plasmon resonance peaks at two different wavelengths by combining plasmon wave from aluminum (Al) and gold (Au) nano-particles (NP). We model the absorption characteristics of two nano particles placed with nano meter scale gap using RF module of COMSOL 5.3 modeling program. The coupled plasmon layer has two peaks at 525 and 640 nm, which are different from the constituent individual metal plasmon layers of Al and Au NPs with peak at 450 nm and 700 nm respectively. Good agreement exits between modeling data with experimental results.
