Luminescence - Wikipedia
Luminescence is a spontaneous emission of radiation from an electronically or vibrationally excited species not in thermal equilibrium with its environment. [1] A luminescent object emits cold light in contrast to incandescence, where an object only emits light after heating. [2]

Luminescence - Wiley Online Library - Analytical Science Journals
Luminescence is an interdisciplinary journal for research on fundamental & applied aspects of all forms of luminescence, covering optics, photonics & electromagnetics.

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.

What is Luminescence, Luminometer, Bioluminescence - Molecular Devices
Luminescence is the emission of light by a substance as a result of a chemical reaction (chemiluminescence) or an enzymatic reaction (bioluminescence). Luminescence detection is optically simpler than fluorescence detection as it does not require a light source or specific optics for excitation.

Luminescence Definition and Examples - Science Notes and Projects
Luminescence is emission of light without appreciable heat. Luminescence is a process by which a substance emits light without becoming noticeably heated. The term comes from the Latin word “lumen”, meaning “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.

Luminescence, fluorescence, and phosphorescence - Explain that Stuff
What is luminescence? What's the difference between luminescence, fluorescence, and phosphorescence? What other types of luminescence are there? Lights in the night; What can we use luminescence for? How fluorescent light beats burglars! Find out more

Bioluminescence: Mechanisms, Applications, and Innovations
These devices utilize bioluminescent elements to detect environmental pollutants or pathogens. By engineering bacteria to emit light in the presence of specific contaminants, scientists have created a tool that signals the presence of harmful substances through changes in luminescence intensity.

luminescence summary | Britannica
luminescence, Emission of light by an excited material through a process not caused solely by a rise in temperature. The excitation is usually achieved with ultraviolet radiation, X-rays, electrons, alpha particles, electric field s, or chemical energy.

3: Molecular Luminescence - Chemistry LibreTexts
Luminescent methods refer to a family of techniques in which excited state species emit electromagnetic radiation. Among luminescent methods are various sub-categories that include the processes of fluorescence, phosphorescence, chemiluminescence, bioluminescence and triboluminescence.
