AbstractA study was conducted to develop a optical response model of highly faceted metal nanoparitcles by using a 3D boundary element method (BEM). The study also can be used to develop model for rod-to-octahedron transition. The BEM for axially symmetric particles can provide optical spectra in decorated nanorods, decahedrons, and nanostars. Gold nanorods were synthesized during the study in water and transfer into N,N-dimethylformamide (DMF). The study also examine the chemical growth of axially symmetric gold nanorods into octahedrons. It was observed during the study that the modeling of the cross-section is simple for a cylinder, while modeling of cross-section of prism require total width and the curvature of the edges. The study concluded that this method is computationally more efficient the DDA of FDTD techniques. © 2008
