Light Up a Nanocluster

Aggregate, Volume 7, Issue 1, January 2026.
Atomically precise metal nanoclusters are ultrasmall aggregates of metal atoms with finely tunable structures. They exhibit broad PL across visible to NIR wavelengths by tuning size, structure, and composition. The review addresses fundamental emission mechanisms and structure–property correlations, evaluating enhancement strategies (ligand ...
