摘要

将金纳米粒子激光注入亚氧化硅中，可显著增强硅纳米晶体的光致发光性能。本研究将通过透射电子显微镜详细探讨嵌入在氧化物基体中的硅纳米晶体与金纳米粒子之间的纳米级相互作用。研究了金纳米颗粒尺寸和与硅纳米晶体的距离对光致发光增强的影响。根据金纳米颗粒的大小和分离距离，观察到硅纳米晶体的光致发光增强了三倍以上，证明了这种直接而快速的基于激光的方法的效率。

Transmission electron microscopy analysis of UV laser implanted gold nanoparticles and their influence on photoluminescence enhancement from silicon nanocrystals

The photoluminescence of silicon nanocrystals is significantly enhanced via laser-based implantation of gold nanoparticles into silicon suboxide. This study is to explore in detail the nanoscale interactions between silicon nanocrystals embedded in the oxide matrix and gold nanoparticles through transmission electron microscopy. The influence of gold nanoparticle size and distance from the silicon nanocrystals is investigated and correlated with photoluminescence enhancement. A more than threefold enhancement in photoluminescence of silicon nanocrystals is observed, depending on the size and separation distance of the gold nanoparticles, demonstrating the efficiency of this straightforward and rapid laser-based method.
