We show surface-enhanced Raman scattering (SERS) on an ordered array of Au nanodots prepared from a highly ordered anodic porous alumina mask. The intensity of SERS signals is strongly dependent on the height of the Au dots, indicating the existence of optimum geometrical structures for SERS. The fabrication process of the nanodot array described in the present study enables easy preparation of SERS substrates.
