Aluminum Nanocrystals: Sub‐3 nm Aluminum Nanocrystals Exhibiting Cluster‐Like Optical Properties (Small 27/2021)

Abstract

Ultrasmall aluminum nanocrystals (<3 nm) with cluster-like optical properties are prepared with a simple and robust synthetic chemical method in article number 2002524 by Xiaoyu Cheng, Sailing He, and co-workers. Phosphonic acids are used to surface-modify and stabilize aluminum nanocrystals in solution. Ultrasmall aluminum nanocrystals exhibit bright photoluminescence in the ultraviolet range, and their lifetime is ultrashort and wavelength-dependent.
