Optical quality and chemical stability: A general nanoparticle synthesis enables the low dispersity and well-defined shape to be inherited from the masked gold cores, yet simultaneously allows the strong plasmonic properties of silver to be exhibited. Protecting the silver with a thin gold layer enables oxidant stability and surface functionality of this system without altering the silver-based optical properties.

银纳米粒子的水金过度生长：将银的等离子体性能与金的功能合并

光学质量和化学稳定性：常规的纳米粒子合成技术可从被掩盖的金核中继承低分散性和轮廓分明的形状，但同时又可展现出银的强等离激元性质。用薄的金层保护银可实现该系统的氧化剂稳定性和表面功能，而不会改变基于银的光学性能。
