RATIONALE: Arsenic tellurides have found important applications in various fields of science, but only a few gold-arsenic tellurides have been reported. Laser ablation synthesis (LAS), a suitable method for the generation of new compounds, has been used to generate clusters from As-Te mixtures, an As-Te glass and Au-As-Te nano-composites.

METHODS: Chalcogenide glass nano-layers prepared via Physical Vapour Deposition – thermal evaporation were characterized using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). LAS with laser desorption ionisation quadrupole ion trap time-of-flight mass spectrometry (LDI QIT TOFMS) was used for the generation and analysis of new Au_xAs_mTe_n clusters. The stoichiometry of the clusters was determined via isotopic envelope modelling.

RESULTS: A simple procedure for the preparation of the Au-As-Te nano-composite was developed. From As-Te mixtures only five binary As_mTe_n clusters were generated, while from a glass layer 10 binary As_mTe_n clusters were identified, because during the deposition of the glass the elements reacted with each other to form a complex three-dimensional (3D) structure. Using LAS on the Au-As-Te nano-composite leads to the formation of six unary Te_n (n=1–6), 16 binary (As_mTe_n and Au_xTe_n), and 31 ternary Au_xAs_mTe_n clusters.

CONCLUSIONS: LAS was demonstrated to be a useful technique for the generation of AuxAsmTen clusters in the gas phase. More As_mTe_n clusters were generated from the deposited glass layers than from As-Te mixtures. Most of the ternary Au_xAs_mTe_n clusters generated from the nano-composite are reported here for the first time.
