Fluorescence and phosphorescence are photoluminescence processes in which material emits photons after excitation.
Fluorescene is the emission of light by a substance that has absorbed light or other electromagnetic radiation.
Phosphorescene is an effect in which some chemicals re-emit light that they absorb.
A visible difference between these two types of luminescence, the ability of phosphorescence materials to glow after the excitation energy source is removed.
