Luminescence is spontaneous emission of light by a substance. It can be caused by electrical energy which results in stress on ceramic.

Depending on the process by which the substance is stimulated by external agents, a light is produced with different shades.

Photoluminescence is the result of absorption of photons, ot results in phosphorescence which lasts longer than fluorescence. Our ceramic slabs lie on the phosphorescence type to liven up your interior.
