超小纳米晶体是传统纳米晶体的一个不断增长的子类,其在通常低于2nm的直径下表现出新的性质。在这篇综述中,我们定义了什么是超小纳米粒子,同时区分超小和魔术大小的纳米粒子。在简要概述了超小纳米粒子,包括超小金簇,我们最近的工作是介绍超小CdSe纳米晶体的光学性质,结构和应用。这种独特的材料由于其平衡的白色发射而在固态照明中具有潜在的应用。本节随后讨论了可以被认为是纳米颗粒和分子之间的模糊边界。
Ultrasmall nanocrystals are a growing sub-class of traditional nanocrystals that exhibit new properties at diameters typically below 2 nm. In this review, we define what constitutes an ultrasmall nanoparticle while distinguishing between ultrasmall and magic-size nanoparticles. After a brief overview of ultrasmall nanoparticles, including ultrasmall gold clusters, our recent work is presented covering the optical properties, structure, and application of ultrasmall CdSe nanocrystals. This unique material has potential application in solid state lighting due to its balanced white emission. This section is followed by a discussion on the blurring boundary between what can be considered a nanoparticle and a molecule.
