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 | 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 & 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 Definition and Examples - Science Notes and Projects
May 14, 2023 · 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 - SpringerLink
Aug 3, 2022 · Luminescence is the emission of optical radiation caused by a non-thermal process [1]. Luminescence is therefore a form of “cold body radiation” or “cold light,” since it does not result from heating (i.e., from a relatively cool material, not above room temperature).
Luminescence physics - Britannica
The excitation energy is transferred to the electrons responsible for luminescence, which jump from their ground-state energy level to a level of higher energy. The energy levels that electrons can assume are specified by quantum mechanical laws.
Luminescence - an overview | ScienceDirect Topics
Luminescence is defined as the phenomenon in which the electronic state of a substance is excited by some kind of external energy and the excitation energy is given off in the form of light. From: Optical Properties of Phosphate and Pyrophosphate Compounds, 2021
3: Molecular Luminescence - Chemistry LibreTexts
Sep 29, 2022 · 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.
