Abstract

A star in the making: Gold nano-hexapods with controlled arm lengths were synthesized by selective growth on the vertices of octahedral Au seeds. Depending on the arm length, their surface plasmon resonance peaks shifted from the visible to the near-infrared region (see picture), which could be readily controlled by varying the amount of HAuCl4, the reaction temperature, or both.
