摘要
A six-rayed star-like nanostructure was prepared by a combination of colloidal self-assembly, thermal sintering and chemical etching, which enables the tuning of both size of the particles and neck diameter. In this nanostructure, six nanotips are arrayed in a symmetric and planar arrangement on a spherical particle. Localized surface plasmon resonance characteristics were also clarified.
