luminescence
n 1: light not due to incandescence; occurs at low temperatures
2: light from nonthermal sources [synonym: {luminescence}, {glow}]

The Collaborative International Dictionary of English v.0.48 (gcide)

Luminescence \Lu`mi*nes"cence\, n. [See {Luminescent}.]
1. (Physics) Any emission of light not ascribable directly to
incandescence, and therefore occurring at low
temperatures, as in phosphorescence and fluorescence or
other luminous radiation resulting from vital processes,
chemical action, friction, solution, or the influence of
light or of ultraviolet or cathode rays, etc.
[Webster 1913 Suppl.]

2. (Zool.)
(a) The faculty or power of producing light by biological
processes, as in the firefly and glowworm. Also called
{bioluminescence}.
(b) The light produced by biological or biochemical
processes. Also called {bioluminescence}.
[Webster 1913 Suppl. PJC]

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
LUMINISCENCE: an immersive visual spectacle through time
Immerse yourself in the secrets of the cathedrals with this immersive multi-sensory experience that will take you on a journey through their history
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

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: 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 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
Technically, luminescence refers to spontaneous emission of electromagnetic radiation (photons) from a material that absorbs energy from a source (external stimulus)
