提出了一种制备溶液三角形纳米银的新方法。采用纳米球光刻技术制备A-纳米颗粒，并将其释放到溶液中。所得到的纳米粒子被不对称功能化以产生分离的单纳米粒子或二聚体对。对银纳米粒子的结构和光学性质进行了表征。用Mie理论和离散偶极子近似法（DDA）来模拟和解释银纳米粒子的光学性质。
A novel method to produce solution-phase triangular silver nanoparticles is presented. A- nanoparticles are prepared by nanosphere lithography and are subsequently released into solution. The resulting nanoparticles are asymmetrically functionalized to produce either single isolated nanoparticles or dimer pairs. The structural and optical properties of Ag nanoparticles have been characterized. Mie theory and the Discrete Dipole Approximation method (DDA) have been used to model and interpret the optical properties of the released Ag nanoparticles.
