No.6（2011）4.LSPR Characterization of Patterned Metal Nanodot Arrays

Elito Kazawa

  For chemical sensors such as bio-sensors and environment monitors, it is useful to introduce a localized surface plasmon resonance (LSPR) phenomenon. This is necessary in order to reduce manufacturing costs for commercialization of the chemical sensor using LSPR. Therefore, substitutions of low cost metals for gold (Au) have been studied. The fabrication processes for nano-patterned metals have been established. Silver (Ag), aluminum (Al), copper (Cu), nickel (Ni) and platinum (Pt) were used in the experiments. Ag arrays and Cu arrays were found to give better quality than Au arrays.
