Article

Methods for forming and diagnosing the parameters of aqueous colloids of noble metals (Ag, Au, Pt) have been developed. We propose to use laser synthesis for obtaining nanosized objects of the above metals in the atmosphere and form colloidal systems of these metals by embedding their ultradisperse particles in aqueous media. We recommend to investigate the parameters of these systems with the use of a combination of direct (scanning electron microscopy, excitation of characteristic radiation by an electron probe) and indirect (absorption spectroscopy, modeling of the extinction efficiency factor on the basis of the Mie theory) diagnostic techniques.
