A relationship exists between the size of the particle and nucleation temperature. There exists an optimum particle size below which nucleation is inhibited. The behaviour of lead iodide thin films as a substrate for ice nucleation is reported in this study. It is found that the supercooling increases with increase in the thickness of the film. But the change in nucleation temperature above 1250 Å is negligible.
