It means giving off light, or glowing.
There are different kinds of luminescence: things can glow because of chemicals in them, because an electric current flows through them, because they are moved in a particular way, and even in ways that we don't know yet.
a low temperature emission of light
it is not photo luminescence it is photoluminescence.Photoluminescence (abbreviated as PL) is a process in which a substance absorbs photons (electromagnetic radiation) and then re-radiates photons.
Bio-Luminescence.
By "physical" quantity, I will "assume" you mean directly measurable. 1. Kinetic Energy 2. Temperature 3. Velocity 4. Heat 'content' 5. Radioactivity 6. Luminescence
Illuminance is another word for 'luminous-flux density', which describes the intensity of the luminous flux hitting a surface. Its SI unit of measurement is the lux, which is a special name given to a lumen per square metre. Luminance is a measure of the intensity of the light reflected by a surface. Its SI unit of measurement is the candela per square metre.
According to Wikipedia: "Thermoluminescence is a form of luminescence that is exhibited by certain crystalline materials, such as some minerals, when previously absorbed energy from electromagnetic radiation or other ionizing radiation is re-emitted as light upon heating of the material." You can read more about this phenomenon, below.
Luminescence - album - was created in 2004.
Journal of Luminescence was created in 1968.
bio-luminescence is light produced by a living organism, such as a firefly
bio-luminescence is light produced by a living organism, such as a firefly
Luminescence is caused by chemical reactions within the substance.
Luminous Luminescence in the Atlas Position was created in 2001.

Luminescence.
There are a few causes of luminescence, but one of the major causes is bioluminescent bacteria. They can be found independently or in a symbiotic relationship with organisms around the world. The other types are luminescence is chemiluminescence, electroluminescence, electrochemiluminescense, photoluminescense, thermoluminescence, and thermoluminescense.
Bioluminescence, chemiluminescence, crystalloluminescence, electroluminescence, photoluminesce and mechanoluminescence are all different types of luminescence. The terms are about different luminescence provenience, in the above other, biological, chemical, crystal, electrical, photo and mechanical.
