    Laser ablation of a silver (Ag) and/or gold (Au) target was performed in liquid ammonia (l-NH3) at 233 K, leading to a formation of nanoparticles. Ag nanoparticles in l-NH3 oxidize to Ag(I) complexes with NH3 ligands. Formation of solvated electrons has not been confirmed. Reference experiments have shown that the production of (e(-))NH3 solvates is hindered by the presence of Ag and Au plates. Ag and Au targets can thus possibly act as electron scavengers in our ablation experiments.
