Theoretical analysis of methods for the colloidal synthesis of monodisperse nanoparticles

Methods for the colloidal synthesis of monodisperse nanoparticles, in which the interrelated processes of nucleation and growth of nanoparticles occurring with variable supersaturation of the solution play a determining role, have been theoretically analyzed. It is supposed that supersaturation is created as a result of a chemical reaction; two reactant feed modes (instantaneous and regularly time-distributed) are considered. Successive steps of growth have been distinguished and described for each mode. Conditions at which the focusing mechanism of the particle-size distribution function is operative are specified.
