Highly luminescent silver nanoclusters with tunable emissions: cyclic reduction–decomposition synthesis and antimicrobial properties
Xun Yuan,Magdiel Inggrid Setyawati,Audrey Shu Tan,Choon Nam Ong,David Tai Leong,Jianping Xie +5 more
TL;DR: Xie et al. as mentioned in this paper proposed a facile aqueous-based synthesis method for highly luminescent Ag nanoclusters (NCs) with tunable emissions, which used a reduction-decomposition-reduction cycle to modify the Ag NC intermediates that were further subjected to size/structure focusing.

A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.
