Photoluminescence (abbreviated as PL) is a process in which a substance absorbs photons (electromagnetic radiation) and then re-radiates photons.LUMINESCENT MEASUREMENTS take advantage of this type of light emitted from LUMINESCENT AGENTS.Any emission of light not ascribable directly to incandescence, and therefore occurring at low temperatures, as in phosphorescence and fluorescence or other luminous radiation resulting from vital processes, chemical action, friction, solution, or the influence of light or of ultraviolet or cathode rays, etc.The excitation sources are ultraviolet radiation and electrons, respectively.
Other types are ionoluminescence, chemiluminescence and others. Bio luminescence is light emitted by living organisms.phosphorescence of certain materials or objects as a result of heating.
