After a decade's efforts, a large amount of highly luminescent metal nanoparticles with different sizes and surface chemistries have been developed. While the luminescence is often attributed to particle size effects, other structural parameters such as surface ligands, valence states of metal atoms and crystallinity of nanoparticles also have a significant influence on emission properties and mechanisms. In this review, we summarized the strategies used to create luminescent gold nanoparticles with sizes from few to millions of atoms and discussed how these structural factors affect their photoluminescence.
经过十年的努力,已经开发出了大量具有不同尺寸和表面化学性质的高发光金属纳米粒子。虽然发光通常归因于粒径效应,但其他结构参数,如表面配体、金属原子的价态和纳米粒子的结晶度,对发射性质和机制也有显著影响。在这篇综述中,我们总结了制备尺寸从几个到几百万个原子的发光金纳米粒子的策略,并讨论了这些结构因素如何影响它们的光致发光。
