Effect of light on the disperse composition of silver hydrosols stabilised by partially decarboxylated polyacrylate

Spherical silver nanoparticles prepared by the reduction of AgNO3 with sodium borohydride in an aqueous solution of partially decarboxylated poly(acrylic acid) coalesce under exposure to light in the course of additional photoreduction of Ag+ cations to form coarse non-spherical particles and their aggregates.
