摘要：
A method for the growth of highly aligned gold nanotriangles (NTs) on conducting glass surfaces is described. This may be described as 'potential-assisted seed mediated growth'. Atomic force microscopy confirms that all the triangles observed are equilateral and are uniformly stacked. The NT-coated glass exhibits intense near-infrared absorption and strong surface-enhanced Raman activity.
