N° 104. — Effet chimique des rayons γ de ⁶⁰Co sur les solutions aqueuses de chlorure d’or

Stabilizer-free nanosized gold sols

“…The vast majority of the processes, however, involve the reduction of gold compounds in solutions. The electrons needed in the latter process can be either generated 'in situ,' as for example in cases where HAuCl 4 solutions are subjected to γ rays [31][32][33], pulse radiolysis [34], ultraviolet [35], and visible [36] radiation, or can be supplied by various reducing chemical species present in solution. Since the redox potential of gold is high, the list of compounds capable to reduce the oxidized metallic species to the elemental state is quite extensive.…”
