Luminescence
Luminescence is emission of light by a substance not resulting from heat; it is thus a form of cold body radiation. It can be caused by chemical reactions, electrical energy, subatomic motions, or stress on a crystal. This distinguishes luminescence from incandescence, which is light emitted by a...

Crystallization
Crystallization is the process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas. Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid...

- "There is a time lag between the achievement of supersaturation in a solution and the appearance of crystalloluminescence flashes from crystal nuclei. The incubation time of crystalloluminescence decreases systematically with the concentration of the solution. A new method based on crystalloluminescence measurements is proposed for the determination of the critical size of the crystal nucleus."
