Notizen:
In this paper we discuss the results of electron microscopic studies of colloidal gold and silver metal particles in the context of a model for their structure and growth. The images obtained are compared with the results of computer simulations for various candidate structures and the actual morphologies present are thereby deduced. With reference to earlier work on inert gas atom clusters we have developed a scheme which models the growth of such particles and enables the structures present to be predicted and rationalized. In particular, we deduce that particles belonging to the icosahedral point group have Mackay-type structures, in agreement with the experimental results. Comparisons are also made between the morphologies adopted by gold, silver, and argon clusters, and the relationship between the bonding in these systems is discussed.
