Hey..!!!
_______________
_______________
luminescence
any giving off of light caused by the absorption of radiant or corpuscular energy and not by incandescence; any cold light; specif., fluorescence or phosphorescence occurring in various chemical, biological, electrical, etc. processes at relatively low temperatures
Origin of luminescence
from Classical Latin lumen, light + -escence
____________
____________
Examples
Gegen, opposite, and schein, shine), an extremely faint luminescence of the sky, seen opposite the direction of the sun.
The chromosphere, which surrounds the photosphere, is a cloak of gases of an average depth of 5000 m., in a state of luminescence less intense than that of the photosphere.
Michelson's experiments therefore argue in favour of the view that the luminescence in a vacuum tube is similar to that produced by phosphorescence where the translatory energy does not correspond to the oscillatory energy - but further experiments are desirable.
He concluded that the gases are due to the decomposition of an organic colouring matter, which has, however, no connexion with the fluorescence or thermo-luminescence of the mineral.
