摘要：

Our original approach consists of observing the dynamics of homogeneous crystal growth throughout the volume of highly supersaturated solutions. The crystal growth is induced at room temperature by a powerful single nanosecond laser pulse and is observed using a synchronized time-resolved optical detection. The supersaturated solution readily transforms after the pulse into a homogeneous gel-like slurry consisting of nanometric crystals. From the analysis of the signals via a kinetic model, we derive the elementary accretion rate constant, the nuclei concentration, and its dependence upon the initial supersaturation concentration. This approach could permit a quantitative study of the homogeneous phase transition dynamics for various other systems.
