Název v původním jazyce

Generation of novel AumSen clusters via laser ablation synthesis. Laser desorption ionisation time-of-flight mass spectrometry

Popis výsledku v původním jazyce

Several gold selenium complexes are known (e.g., [Au 2 (Se 2 )(Se 3 )] 2- , [Au 2 (Se 2 )(Se 4 )] 2- and [Au 2 Se 2 (Se 4 ) 2 ] 2- ). Minerals such as fischesserite (Ag 3 AuSe 2 ), kurilite ((Au,Ag) 2 (Te,Se,S) 2 ) and petrovskite ((AuAg)(S,Se)) are found in nature. Laser desorption ionisation time-of-flight mass spectrometry (LDI TOF MS) is powerful technique to generate and study clusters formed during laser ablation of various materials leading to metal chalcogenides [1] or gold carbides [2], for example. The aim of this work is to study the generation of Au m Se n clusters via laser ablation synthesis (LAS) using mixtures of GNPs (or auric acid) with selenium in various molar ratios as precursors. We have found that GNPs are chemisorbed on seleniumsurface leading to the formation of a kind of nano-composite as confirmed by scanning electron microscope (SEM) analysis.
