Preparation of silver nanoparticles on ITO surfaces by a double-pulse method

The influence of pulse parameters of a potentiostatic double-pulse on the size distribution of silver clusters was investigated. The silver clusters were deposited from a cyanide-containing electrolyte onto indium-tin oxide electrodes. Clusters with particle diameters of 100-300 nm can be prepared on a time scale of minutes. A model is presented, which is able to explain the experimental results. (C) 2000 Elsevier Science B.V. All rights reserved.
