title: Synthesis of silver nanodisks using polystyrene mesospheres as templates.
abstract: We report the synthesis of Ag nanodisk using polystyrene mesospheres as templates. TEM measurements show that the average disk thickness is 9.0 +/- 1.0 nm and the diameter is 36 +/- 8 nm. The particles exhibit an intense electronic spectrum that differs markedly from that for spheres (purple vs yellow solutions). We present electromagnetic theory calculations which exhibit a qualitative match with the observed spectrum, enabling us to assign several of the plasmon resonance features.
