Abstract

Luminescence processes in molecules can be classified according to the source from where the excitation energy is derived. In photoluminescence, which encompasses fluorescence and phosphorescence, excitation is achieved by the absorption of light by the potentially luminescent molecule. In chemiluminescence, excitation occurs as the result of an energetic chemical reaction.
