Implication

Experimental study observes sub-microsecond spontaneous nucleation delays during laser-induced liquid vaporization, highlighting superheating dynamics at film interfaces.

Key Points

To measure transient interfacial temperatures and monitor spontaneous nucleation dynamics during the pulsed excimer-laser-induced explosive vaporization of thin liquid films.
Irradiated pure and mixed liquid films atop amorphous silicon on fused quartz substrates with an ultraviolet excimer pulsed laser at fluences below and above the spontaneous nucleation threshold.
Monitored optical transmission signals across varying silicon film thicknesses and calibrated interface temperatures using a one-dimensional diffusion model and characteristic matrix theory.
Calibrated transient interface temperatures showed consistent agreement with theoretical calculations and established reference values for superheated liquids.
Spontaneous nucleation delay times were estimated to be ≲ 1 μs, aligning closely with typical timeframes observed in droplet explosion experiments.
