提出了一种利用双靶溅射法制备银金合金纳米粒子的新方法。结果表明，银-金固溶体合金作为单独的纳米粒子的形成。所施加的靶电流的变化允许NP组成的微调，并且因此允许合金NP的光学性质的变化。该方法提供了对每个金属靶的溅射参数的高度独立的控制，从而允许操纵NP组成、尺寸和光学性质。(C)2016爱思唯尔B. V.保留所有权利。
A new approach using double target sputtering into liquid is proposed to synthesize Ag-Au alloy nanoparticles (NPs). The results reveal the formation of Ag-Au solid solution alloy as individual NPs. Variation of the applied target current allows fine tuning of the NP composition, and, therefore, variation of optical properties of the alloy NPs. The method offers highly independent control of sputter parameters for each metal target, thereby allowing manipulation of the NP composition, size and optical properties. (C) 2016 Elsevier B.V.
