Lyoluminescence refers to the emission of light (nonfiction) while dissolving a solid into a liquid.

The most common lyoluminescent effect is seen when solid samples which have been heavily irradiated by ionizing radiation are dissolved in water.

Many gamma-irradiated substances are known to lyoluminesce, including spices, powdered milk, soups, cotton, and paper.

While the broad variety of materials which exhibit lyoluminescence confounds explanation by a single common mechanism, there is a common feature to the phenomenon: the production of free radicals in solution.
