Phosphorescence is a radiative transition involving a change in the spin multiplicity of a molecule. Because of this change, the radiative transition is delayed, and the phosphorescent material glows a while after the incident illumination stops. Because of this, phosphorescent materials are most commonly called "glow-in-the-dark".
In other words, certain substances can absorb the energy from radiation such as light for brief times in their electrons. The release of this energy is what causes the glowing effect when the light is gone.
Such material, generally made from phosphors, is used in everything from plastics to stickers.
