含Au、Ag或Cu的复合物的相对吸收强度为长扁（a>B=c）、扁（aa=c）和正扁（B）。我们发现，在模拟中，ortho-prolate粒子提供了最大的强度每单位体积分数的金属。当仅考虑颗粒形状时，Sers基底预期的增强程度近似与吸收强度成比例。我们还提出了一种简单的方法，通过模板合成法制备Sers衬底。(C)1997《冶金学报》
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.
