Ionic liquids are a fascinating class of solvents which due to their usually negligible vapour pressures are well suited to vacuum studies.Their usually wide electrochemical windows allow by classical electrodeposition to make various reactive elements like Si,Ge,Al and other ones and they can dissolve a variety of different precursors.In a pioneering paper we could show that an argon plasma ?burns“ stably over an ionic liquid and that the electrons of the plasma can reduce silver ions to silver nanoparticles at the interface plasma / ionic liquid [1].In 3 successive papers we were able to show that copper nanoparticles can be made as well and that there is a slight dependence of the particles on the employed ionic liquid [2-4].
