| The synthesis of inorganic nanocrystals with controllable shape is an important goal of modern materials chemistry and one that has been characterized by rapid progress. An extraordinary synthesis of nanostructures, including, rods, triangular prisms, disks, and even branched tetra-pods, can now be generated often in high yield. Beyond their aesthetic appeal, these new structures are compelling for multiple fundamental and practical technological reasons. Herein, we report the wet-chemical synthesis of several anisotropic nanostructures and systemically study the intrinsic shape-dependent properties by comparison of experimental observations and theoretical simulations. In addition, we show that these structures are desirable for emerging applications entailing bio-labels, chemical sensing, and surface enhanced Raman scattering (SERS). |
