luminesans teriminin Türkçe İngilizce sözlükte anlamı
- (Tıp) luminescence
- showing increase
- Any emission of light not ascribable directly to incandescence, and therefore occurring at low temperatures, as in phosphorescence and fluorescence or other luminous radiation resulting from vital processes, chemical action, friction, solution, or the influence of light or of ultraviolet or cathode rays, etc
- Luminescence is a soft, glowing light. Lights reflected off dust-covered walls creating a ghostly luminescence. a soft shining light. Process by which an excited material emits light in a process not caused solely by a rise in temperature. The excitation is usually achieved with ultraviolet radiation, X rays, electrons, alpha particles, electric fields, or chemical energy. The colour, or wavelength, of the light emitted is determined by the material, while the intensity depends on both the material and the input energy. Examples of luminescence include light emissions from neon lamps, luminescent watch dials, television and computer screens, fluorescent lamps, and fireflies. See also bioluminescence; fluorescence; phosphorescence
- {i} quality of being luminescent, emitting of light, glowing (not through heat)
- Production of light
- light, ability to produce light
- Any emission of light that cannot be attributed merely to the temperature of the emitting body
- Luminous dials first appeared during the Great War when soldiers needed to tell the time in the dark Early forms used Zinc Sulphide compound agitated by a radioactive salt It was painted on hands and was potentially dangerous to those applying it Its use was banned in the 50's, since Tritium, a substance with a low radio activity, replaced it Other methods have been devised Timex's 'Indiglo' uses electronic luminescence; a button on the side of the case causes a tiny current from the battery to the electrodes and gives off energy in the form of light Seiko uses fluorescent material on the dial, activated by any exposure to light
- – The emission of light that does not derive energy from the temperature of the emitting body
- Having the power to emit rays of light A luminescent material is deposited on numbers and hands in order to read the time in the dark
- The part of the video signal that controls the luminance/brightness of the picture Also known as the "Y" portion of the component signal
- Any emission of light at temperatures below that required for incandescence
- emission of light from a body when its atoms are excited by means other than raising its temperature Short-lived luminescence is called fluorescence
- light from nonthermal sources light not due to incandescence; occurs at low temperatures
- light not due to incandescence; occurs at low temperatures
- The light thus produced; luminosity; phosphorescence
- The emission of light by sources other than a hot, incandescent body Among several types are chemiluminescence, electroluminescence, and triboluminescence, which are produced, respectively, by chemical reactions, electric discharges, and the rubbing or crushing of crystals
- The faculty or power of voluntarily producing light, as in the firefly and glowworm
- Light emission that cannot be attributed merely to the temperature of the emitting body, but results from such causes as chemical reactions at ordinary temperatures, electron bombardment, electromagnetic radiation, and electric fields
