Composition Studies for Unknown Gold Nanoclusters


EMSL Project ID
48105

Abstract

The composition of novel atomic-precise gold clusters protected by phosphine ligand is crucial for the potential optical or catalytic applications of this new material family. The high-resolution mass spectroscopy, especially the isotopic pattern, has proven to be one of the most powerful tools to obtain the composition, as well as other valuable information. The mass spectroscopy in EMSL is a state-of-the-art machine which would be very useful for studying our unknown gold clusters.
