Abstract

The etching mechanism of silver nanoparticles was investigated. Though a strong binding agent to silver and an oxidising agent synergistically etch the nanoparticles, the balanced etching power has to be optimized to generate luminescent silver nanodots. This indicates that active centres facilitate the formation of nanodots.

摘要

研究了银纳米颗粒的蚀刻机制。虽然一种与银结合力强的试剂和一种氧化剂协同蚀刻纳米颗粒，但必须优化平衡蚀刻能力以生成发光银纳米点。这表明活性中心有助于纳米点的形成。
