Abstract
The time evolution of colloidal gold particles in the nanometric regime has been investigated by employing electron microscopy and electronic absorption spectroscopy. The particle size distributions are essentially Gaussian and show the same time dependence for both the mean and the standard deviation, enabling us to obtain a time-independent universal curve for the particle size. Temperature dependent studies show the growth to be an activated process with a bamer of about 18 kJ mol-1. We present a phenomenological equation for the evolution of particle size and suggest that the growth process is stochastic.
