摘要: Copper–tin (CuxSn1−x) nanocluster is a promising system for gas sensing applications, mainly because of its sensitivity and selectivity H2S. In this work, pure Sn Cu as well composite CuxSn1−x nanoclusters were synthesized using the dc magnetron sputtering condensation technique. Nanoclusters with different to ratios produced by changing ratio in target. The dependence Sn, Cu, nanoclusters’ size distribution on various source parameters, such inert flow rate aggregation length, has been investigated detail. results show that increases, mean increases decreases while then CuxSn1−x. could be understood terms contribution percentage formation mechanism. Furthermore, work demonstrates ability tuning composition proper optimization operation conditions.
