Findings from Masaryk University Provides New Data on Rapid Mass Spectrometry (Generation of AupAgqTer clusters via laser ablation synthesis using Au-Ag-Te nano-composite as precursor: quadrupole ion-trap time-of-flight mass spectrometry)

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Rapid Mass Spectrometry. According to news reporting originating from Brno, Czech Republic, by NewsRx correspondents, research stated, "Metal tellurides have applications in various fields of science and technology but only a few gold-silver tellurides have been reported. The laser ablation synthesis (LAS) method allows the preparation of nano-materials from solid substrates."

Our news editors obtained a quote from the research from Masaryk University, "Therefore, this method was selected to synthesise some gold-silver tellurides. Laser desorption ionisation quadrupole ion trap time-of-flight mass spectrometry (LDI QIT TOF MS) was used for the generation of new AupAgqTer clusters. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) were used to characterise the materials. The stoichiometry of the clusters generated was determined via collision-induced dissociation (CID) and modeling of isotopic patterns. Chemisorption of gold and silver nano-particles on tellurium powder led to the formation of a new kind of Au-Ag-Te nano-composite. The LDI of this nano-composite yielded nine unary (Ag-q, Te-r), 40 binary (AupTer and AgpTer) and 78 ternary clusters. The stoichiometry of these novel AupAgqTer clusters is reported here for the first time. The new Au-Ag-Te nano-composite was found to be a more suitable precursor for the generation of clusters than the mixtures of the elements. TOF MS was shown to be a useful technique for following the generation of gold-silver tellurides."

According to the news editors, the research concluded: "Knowledge of the cluster stoichiometry could accelerate the further development of novel high-tech materials such as chalcogenide glasses."
