金（Au）在离子液体（IL）上的溅射沉积导致高度分散的Au纳米颗粒的形成，而不需要额外的化学物质，例如还原剂和/或稳定剂。在1-乙基-3-甲基咪唑四氟硼酸盐中的Au纳米颗粒的平均直径（d（av））为5.5 nm，标准偏差（σ）为0.86 nm，而溅射沉积到N，N，N-三甲基-N-丙基铵双（三氟甲磺酰基）酰亚胺上导致形成小得多的Au纳米颗粒，d（av）为1.9 nm，σ为0.46 nm。溅射时间的延长导致离子液体中Au纳米颗粒的浓度增加，但没有引起其尺寸的显著变化。(c)2006年，美国物理学会。
Sputter deposition of gold (Au) onto ionic liquids (ILs) resulted in the formation of highly dispersed Au nanoparticles without additional chemical species, such as reducing and/or stabilizing agents. The Au nanoparticles in 1-ethyl-3-methylimidazolium tetrafluoroborate had an average diameter (d(av)) of 5.5 nm with a standard deviation (sigma) of 0.86 nm, while sputter deposition onto N,N,N-trimethyl-N-propylammonium bis(trifluoromethanesulfonyl)imide resulted in the formation of much smaller Au nanoparticles with d(av) of 1.9 nm and sigma of 0.46 nm. Prolongation of sputtering time results in a higher concentration of Au nanoparticles in ILs, but did not cause a remarkable change in their size. (c) 2006 American Institute of Physics.
