Supramolecular self-assembly of morphology-dependent luminescent Ag nanoclusters

26 July, 2014 - 15:17

Chem. Commun., 2014, 50,9565-9568
DOI: 10.1039/C4CC03913K, CommunicationXiaofang Jia, Jing Li, Erkang Wang
Self-assembled thiolated Ag nanoclusters (NCs) were facilely synthesized through one-pot microwave-assisted reaction. By the mechanism of aggregation induced emission, the quantum yield of the AgNCs is as high as 25.6%. The as-prepared AgNCs give access to intriguing photophysical features and multicolour emission, which are found to be related to their fascinating supramolecular structures.
