Abstract

The experimental method of determining the concentration of nanoscale inhomogeneities (nanoparticles and nanopores in the two-phase systems) by the method of small-angle X-ray scattering has been developed. Results demonstrate the possibility of controlling the bulk concentrations of gold nanoparticles formed from dopant HAuCl4 by UVinduced reduction of Au+3 to Au0 in polymer solutions. It was first shown that the completeness of the transition from ion gold into nanoparticles depends on the nature of the polymer.
