These observations prove gold precipitation even when aqueous HAuCl4 solutions are exposed to low dose rates, which is further indicated by gold reduction observed in photon-mediated radiolysis caused by lasing, UV exposure, or γ-irradiation, at dose rates many orders of magnitude lower than those utilized in typical LP-TEM experiments. Moreover, the experimental findings demonstrate that beam effects must not be neglected for any experimental investigations of liquid phases using ionizing radiation even during low-dose exposure in standard laboratory conditions.
