Generation of new Ag_mTe_n clusters via laser ablation synthesis using Ag‐Te nano‐composite as precursor. Quadrupole ion trap time‐of‐flight mass spectrometry

Abstract

LAS with TOFMS detection was proven to be a powerful technique for the generation of silver telluride clusters. Knowledge of the stoichiometry of the generated clusters might facilitate the further development of novel high-tech silver tellurium nano-materials.

Structural elucidation of AgAsS2 glass by the analysis of clusters formed during laser desorption ionisation applying quadrupole ion trap time‐of‐flight mass spectrometry

“…A series of clusters with an increasing number of Ag 2 S units was observed. The general stoichiometry of the clusters in the series was found to be Ag m AsS x (m = even numbers in the range 16, 20-32 while the value of x was in the range [10][11][12][13][14][15][16][17][18] or MS n analysis MS 2 spectra were recorded for the peaks at m/z~1593.93, 1343.83,~1098.18, and~850.35 via collision-induced dissociation (CID) using argon. For example, the product ion spectrum obtained for the cluster at m/z 1343.83 is shown in Fig.…”

“…[14] Quadrupole ion trap time-of-flight mass spectrometry (QIT-TOFMS) is a powerful technique for following the generation of clusters from various solid materials, [15][16][17] and it has been used to study the generation of new compounds. [15][16][17][18][19][20] The detailed structure of AgAsS 2 glass has, up to now, not been characterised and therefore the aim of this work was to study clusters generated during the laser ablation of AgAsS 2 glass and, via determination of their stoichiometry, to elucidate the structure of this glass.…”
