Luminescence - Wikipedia
Luminescence occurs when a system absorbs or gains energy, populating excited electronic and/or vibrational states, and then returns to a lower-energy state by emitting a photon.
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 covering optics, photonics and electromagnetics, providing a forum for the publication of research on fundamental and applied aspects of all forms of luminescence.
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 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.
Introduction to Luminescence and Luminescent Materials
Incandescence refers to the emission of light in the visible/infrared region when a substance is heated at a very high temperature. These are called thermal radiation. On the other hand, luminescence refers to the emission of light at normal or low temperatures.
Luminescence - an overview | ScienceDirect Topics
Technically, luminescence refers to spontaneous emission of electromagnetic radiation (photons) from a material that absorbs energy from a source (external stimulus).
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.
Luminescence - Laser Scientist
Luminescence is a fascinating phenomenon where substances emit light without the need for high temperatures. Unlike thermal radiation, which is light emitted due to heat, luminescence occurs at much lower temperatures, earning it the nickname “cold light.”
