The emission of light that does not derive power from the temperature regarding the emitting human body, as with phosphorescence, fluorescence, and bioluminescence. Luminescence is brought on by chemical, biochemical, or crystallographic modifications, the motions of subatomic particles, or radiation-induced excitation of an atomic system.
The light so emitted.
Any emission of light that simply cannot be attributed simply to the temperature of the emitting body.
Any emission of light maybe not ascribable right to incandescence, therefore occurring at reasonable temperatures, such as phosphorescence and fluorescence or other luminous radiation resulting from important processes, chemical activity, friction, solution, and/or influence of light or of ultraviolet or cathode rays, an such like.
The faculty or energy of creating light by biological procedures, as with the firefly and glowworm. Also known as bioluminescence.
The light made by biological or biochemical processes. Also known as bioluminescence.
start to see the quotation.
The emission of light from reasons other than that which creates incandescence.
light not because incandescence; happens at reasonable temperatures
