Определение phosphorescence в Английский Язык Английский Язык словарь
The emission of light without any perceptible heat; the quality of being phosphorescent
We saw a round red sun rise over the City, paint the glassy towers with phosphorescence and, as it brightened and lost its shape, sprinkle across the sky feathers of pink and lilac.
Phosphorescence is a glow or soft light which is produced in the dark without using heat. a slight steady light that can only be noticed in the dark. Emission of light from a substance exposed to radiation and persisting as an afterglow after the exciting radiation has been removed. Unlike fluorescence, in which the absorbed light is emitted about 10^-8 second after excitation, in phosphorescence the extra energy absorbed is stored in metastable states and reemitted later. Phosphorescence may last from about 10^-3 second to days or even years. The term phosphorescence is often applied to luminescence of living organisms, as well
Luminescence that persists after a light source has been removed Materials such as phosphors or phosphorogens are activated from a light source to emit the light in the form of photons of light
The continued emission of light by a substance after the exciting radiation has been discontinued
Emission of visible light by a substance, such as a mineral, that is exposed to ultraviolet light and absorbs radiation from it The light appears in the form of glowing, distinctive colors The emission continues after the exposure to ultraviolet light ends
Greenish light given off by certain microscopic marine organisms when agitated by movement in the water; emission of light without burning or by very slow burning without appreciable heat, as from the slow oxidation of phosphorous
