Аннотация: Physical mechanisms of the reasons for dramatic (up to 10(8) times) acceleration of the aggregation of sol metals under the action of light are proposed for the first time. These mechanisms were classified with allowance for the procedure of sol stabilization and type of dispersion medium; their comparative analysis was performed uПоказать полностьюsing the main types of silver sols as the most convenient model medium. Mechanisms proposed are based on the current notions of the theory of coagulation kinetics and stability of sols with account of interfacial processes, as well as of the theory of photoeffect corrected for the influence of dispersion medium and the amplification of local electromagnetic fields inherent in colloidal structures with fractal geometry.
