Luminescence - Wikipedia
Luminescence is a spontaneous emission of radiation from an electronically or vibrationally excited species not in thermal equilibrium with its environment. [1]
Luminescence | Definition, Examples, Types, & Facts | Britannica
Luminescence, emission of light by certain materials when they are relatively cool. It is in contrast to light emitted from incandescent bodies, such as burning wood or coal, molten iron, and wire heated by an electric current.

Luminescence Definition and Examples - Science Notes and Projects
Luminescence is light emission that does not result from heat, unlike incandescence. It occurs when electrons absorb energy and release it as light while returning to a lower energy state.
Luminescence - Wiley Online Library
Luminescence is an interdisciplinary journal for research on fundamental & applied aspects of all forms of luminescence, covering optics, photonics & electromagnetics.
LUMINESCENCE Definition & Meaning - Merriam-Webster
The meaning of LUMINESCENCE is the low-temperature emission of light (as by a chemical or physiological process); also : light produced by luminescence. How to use luminescence in a sentence.
Luminiscence Type - an overview | ScienceDirect Topics
Luminescent refers to a property of materials that emit (near)-visible light as a result of energy conversion, often initiated by electromagnetic radiation, electrical, or chemical excitation, which energizes the atoms and causes them to release excess energy in the form of electromagnetic radiation.
Luminescence, fluorescence, and phosphorescence - Explain ...
That's an example of what we call photoluminescence: luminescence made by light. But you can make things give off light by exciting their atoms with many other kinds of energy. You give the atoms one kind of energy (light, heat, sound, or whatever) and they give the same energy back to you as light.
What is Luminescence, Luminometer, Bioluminescence
What is luminescence? Luminescence is the emission of light by a substance as a result of a chemical reaction (chemiluminescence) or an enzymatic reaction (bioluminescence).
LUMINESCENCE definition | Cambridge English Dictionary
The ocean often emits a visible glow, or luminescence, which extends for miles at night. They toil over the perfect shade of pigment, the architectural details of an elaborate building, the luminescence of a wine glass.
