Abstract

A photo-Fenton-like process can promote the agglomeration and LSPR red-shifting of ultra-small gold nanoparticles by triggering a crosslink-degradation pathway that involves the surface coating, Fe(iii)-citrate and hydrogen peroxide. Applications may range from controlled photo-deposition of active materials to asynchronous sensing technologies to light-focused microfabrication.

摘要

一种类光芬顿过程可以通过触发涉及表面涂层、柠檬酸铁（III）和过氧化氢的交联降解途径，促进超小金纳米颗粒的团聚和局域表面等离子体共振（LSPR）红移。其应用范围可能从活性材料的可控光沉积到异步传感技术，再到光聚焦微加工。
