Sputtering onto liquids: how does the liquid viscosity affect the formation of nanoparticles and metal films?

Autor: Anastasiya Sergievskaya, Rémi Absil, Adrien Chauvin, Kirill V. Yusenko, Jozef Veselý, Thomas Godfroid, Stephanos Konstantinidis

Publikováno v: Physical chemistry chemical physics : PCCP.

This paper reports on the effect of the solvent viscosity on the formation of gold nanoparticles (Au NPs) during the sputtering onto liquid (SoL) process. All other parameters related to the plasma and the host liquid are kept constant. SoL is a simp
