  "abstract": "This dedicated optical emission spectroscopy (OES) study aims to improve the understanding of low-pressure sputtering onto liquids used for the production of nanoparticle (NPs) suspensions. In this work, ruthenium (Ru) nanoparticles are synthesized in polyethylene glycol contained in a glass vial positioned outside the deposition reactor. The successful application of OES at the plasma-liquid interface enabled the determination of several key parameters. The gas temperature exceeding 660 K was measured using two different approaches, namely Doppler broadening and the analysis of the OH(A X II 22 )(0-0) rotational spectra. Such values of temperature inherently enhance the PEG evaporation, which is consistent with the decrease in the energy of hydrogen species to (9.3 ± 0.2) eV above the liquid surface. This value was obtained from the analysis of the H line profile and the so-called excessive Doppler broadening. Furthermore, the electric field above the plasma-liquid interface was determined to be (29 ± 4) V/cm through measurements of the Stark shift of the Ar line at 541.047 nm. Finally, by investigating the electric field, the plasma-liquid chemistry, and the dynamic properties of the surface, this study provides new insights that contribute to a better understanding of this physical synthesis technique.",
