Luminescence - Wikipedia
Luminescence is the emission of optical radiation (ultraviolet, visible, or infrared) by a substance due to a process other than heating. [1] In the broad chemical/photochemical sense, luminescence is the spontaneous emission of radiation from an electronically or vibrationally excited species that is not in thermal equilibrium with its ...

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. Our scope includes but is not limited to photoluminescence, chemiluminescence, electroluminescence, bioluminescence, and sonoluminescence, with a particular focus on fluorescence- and ...
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 may be seen in neon and fluorescent lamps; television,

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. After absorbing energy, an atom is in an excited state, from which it tends to stabilize itself by losing this absorbed energy. The atom can lose this excess ...
