Description
Summary:The results of investigation of the fluorescence of carboxylated polystyrene microspheres in the process of photochemical synthesis of gold nanoparticles are presented. The introduction of an aqueous solution of hydrogen tetrachloroaurate (III) into an unirradiated polymer dispersion causes a decay of the excimer fluorescence in polystyrene at 335 nm. UV irradiation (λ exc = 254 nm) of polystyrene dispersions in the presence of AuCl 4 − ions leads to the formation of metal particles, which occurs after an induction period and affects the polystyrene fluorescence.
