Chemiluminescence differs from fluorescence or phosphorescence in that the electronic excited state is the product of a chemical reaction rather than of the absorption of a photon. It is the antithesis of a photochemical reaction, in which light is used to drive an endothermic chemical reaction.
Bioluminescence is the emission of light during a chemiluminescence reaction by living organisms. [1] Bioluminescence occurs in diverse organisms ranging from marine vertebrates and invertebrates , as well as in some fungi , microorganisms including some bioluminescent bacteria , dinoflagellates and terrestrial arthropods such as fireflies .
Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a kind of luminescence produced during electrochemical reactions in solutions. In electrogenerated chemiluminescence, electrochemically generated intermediates undergo a highly exergonic reaction to produce an electronically excited state that then emits light upon relaxation to a lower-level state.
Chemiluminescence is the emission of light through a chemical reaction. It contrasts with fluorescence , which is excited by a light source. During chemiluminescence, the vibrationally excited product of an exoergic chemical reaction relaxes to its ground state with the emission of photons . [ 1 ]
Luminol (C 8 H 7 N 3 O 2) is a chemical that exhibits chemiluminescence, with a blue glow, when mixed with an appropriate oxidizing agent.Luminol is a white-to-pale-yellow crystalline solid that is soluble in most polar organic solvents but insoluble in water.
But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering. But that same phenomenon can also sometimes make skies ...
As the definition does not fully describe the phenomenon, quantum mechanics is employed where it is defined as there is no change in spin multiplicity from the state of excitation to emission of light. [2] Phosphorescence, traditionally defined as persistent emission of light after the end of excitation. As the definition does not fully ...
