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

May 27, 2023 · Luminescence is the production of light by atoms that become excited by various kinds of energy. Learn about the different types of luminescence, such as fluorescence, phosphorescence, bioluminescence, and more, and see how they work in nature and technology.
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.
May 14, 2023 · Luminescence is a process by which a substance emits light without becoming noticeably heated. The term comes from the Latin word “lumen”, meaning “light.” In contrast, incandescence is light resulting from heating a material so that it emits blackbody radiation.
Luminescence is an umbrella term for entities that emit light upon energetic excitation without heating. Luminescence bionanomaterials have broad applications, including those in optical devices such as photovoltaics [28], security [29], lighting [30], lasers [31], diagnostic sensing [32], color display [33], and for in vivo imaging [34].
Luminescence - Luminescence physics: The emission of visible light (that is, light of wavelengths between about 690 nanometres and 400 nanometres, corresponding to the region between deep red and deep violet) requires excitation energies the minimum of which is given by Einstein’s law stating that the energy (E) is equal to Planck’s ...
