Paper Abstract

The paper studies the process of photostimulated aggregation of ultradispersoidal silver particles into fractal clusters observed in some colloidal solutions irradiated by different types of pulsed and continuous-wave lasers and by a nonmonochromatic light. A photoaggregaton mechanism has been proposed, based on mutual charging of different-size particles in a conducting medium when the Fermi potentials become equal because of their dimensional dependence.
