| Description | LAS of gold arsenides was performed using nano gold (NG) and arsenic as precursors. The clusters formed during laser desorption ionisation (LDI) were analysed by mass spectrometry using a quadrupole ion trap and reflectron time of flight analyser to determine the stoichiometry. UV VIS spectrophotometry was used to follow possible hydrothermal synthesis of gold arsenides. Over 450 species of gold arsenide clusters and 212 mixed chlorinated AumAsnClx clusters were detected and their stoichiometry determined. |
