Graphic abstract: Effect of pH on radiation-induced synthesis of gold nanoparticles in solutions of poly(1-vinylimidazole)–Au<sup>III</sup> complexes

Abstract: Irradiation of an aqueous ethanol solution of poly(1-vinylimidazole) containing Au^III ions with X-rays leads to the generation of gold nanoparticles (AuNPs) with an average size determined by the pH value of the medium. The results obtained demonstrate a prominent example of the formation of stable ultrasmall AuNPs (<2 nm) at neutral pH.

Keywords: gold nanoparticles, poly(1-vinylimidazole), radiation-chemical synthesis, metal–polymer complexes, plasmon resonance, pH control.
