What is photoluminescence?

Photoluminescence is a physical process whereby a material absorbs photons from a light source and re-emits them. To achieve this, the body is subjected to radiation of varying intensity, which excites the electrons present in the substance. These electrons store the light, store the energy and release it when there is a total absence of light.

Thanks to photoluminescence, the substance can be recharged indefinitely by daylight or artificial lighting. Our LuminoKrom® photoluminescent paint exploits exactly this physical phenomenon.
