Photostimulated aggregation of ultradispersoidal silver particles into fractal clusters

Abstract

In this paper, studies of the photostimulated aggregation of ultradispersoidal silver particles into fractal clusters observed in colloidal solutions irradiated by different types of pulsed and continuous-wave lasers and by non-monochromatic light are described. A photoaggregation mechanism is suggested, on the basis of mutual opposite charging of different sized particles due to the equalization of their size-dependent Fermi energies in a conducting medium.
