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 - 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 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, fluorescence, and phosphorescence - Explain that Stuff
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.
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.
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: types and mechanism - ScienceDirect
Luminescence is the phenomenon of emission of light from materials owing to the transitions of electrons from the excited energy state (higher energy) to the ground state (lower energy) after excitation by an external source of energy.
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.
Decoding Luminescence Vs Fluorescence - Smore Science
Luminescence and fluorescence are types of light emission that occur in certain materials. While interesting, they are relatively straightforward physical phenomena with well-understood mechanisms in modern physics. The essence of luminescence is that substances emit light without being heated.
