title: Fabrication of arrayed metallic nano-particles on a flexible substrate for inducing localized surface plasmon resonance.
abstract: This paper presents a new method for fabricating periodic arrays of metallic nano-particles on flexible substrates. This method is based on metallic film contact transfer method and high-power pulsed laser annealing. Experiments have been carried out to produce arrayed metallic nano-particles oriented in a hexagonal pattern. The nano-particle size is 70 nm in diameter and the center-to-center pitch of the hexagonal array is 400 nm. Large-area patterning and fabrication of these arrayed nano-particles can be easily achieved up to an area size of few cm(2). Besides, composite or compounded metallic nano-particle arrays can also be produced using different metal materials. The localized surface plasmon resonance (LSPR) effects induced by the fabricated arrays of nano-particles are experimentally observed and quantitatively measured. Numerical simulation on these LPSR effects is performed and the simulation results are in good agreement with experimental data.
