The relative absorption intensities of composites containing Au, Ag or Cu prolate (a>b=c), oblate (aa=c) and ortho-oblate (b ortho-prolate and prolate --> oblate. We found that in simulations, ortho-prolate particles provided the greatest intensity per unit volume fraction of metal. When considering particle shape only, the degree of enhancement expected from SERS substrates is approximately proportional to the intensity of absorption. We also propose a simple means of fabricating SERS substrates by means of the template synthesis method. (C) 1997 Acta Metallurgica Inc.
