Synthesis of cationically charged photoluminescent coinage metal nanoclusters by sputtering over a liquid polymer matrix

Abstract

This study demonstrates a novel synthesis of cationically charged photoluminescent noble metal nanoclusters of Au, Ag, and Cu; these are known plasmonic elements utilizing 11-mercaptoundecyl-N,N,N-trimethyl ammonium bromide as a stabilizing and capping ligand via sputtering deposition over a liquid polymer matrix.
