Photochemical Synthesis of Gold Nanoparticles in Latexes

摘要

Gold nanoparticles in aqueous dispersions of 100-nm polystyrene microspheres were prepared by photochemical synthesis under exposure to monochromatic light with an excitation wavelength of 254 nm. The kinetic relationships in formation of gold nanoparticles were examined in relation to the H[AuCl_4] and polymer concentration in the photolyte.
