n. 无热光,冷光,发光

无热光,冷光,发光

luminescence
亮度

luminescence
n 1: light not due to incandescence; occurs at low temperatures
2: light from nonthermal sources [synonym: {luminescence}, {glow}]

Luminescence \Lu`mi*nes"cence\, n. [See {Luminescent}.]
1. (Physics) 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.
[Webster 1913 Suppl.]

2. (Zool.)
(a) The faculty or power of producing light by biological
processes, as in the firefly and glowworm. Also called
{bioluminescence}.
(b) The light produced by biological or biochemical
processes. Also called {bioluminescence}.
[Webster 1913 Suppl. PJC]

  • Luminescence | Definition, Examples, Types, Facts | Britannica
    luminescence, emission of light by certain materials when they are relatively cool It is in contrast to light emitted from incandescent bodies, such as burning wood or coal, molten iron, and wire heated by an electric current
  • Luminescence Definition and Examples - Science Notes and Projects
    Luminescence is light emission that does not result from heat, unlike incandescence It occurs when electrons absorb energy and release it as light while returning to a lower energy state
  • LUMINESCENCE Definition Meaning - Merriam-Webster
    The meaning of LUMINESCENCE is the low-temperature emission of light (as by a chemical or physiological process); also : light produced by luminescence How to use luminescence in a sentence

    Technically, luminescence refers to spontaneous emission of electromagnetic radiation (photons) from a material that absorbs energy from a source (external stimulus)
  • Luminescence | Springer Nature Link
    Luminescence is the emission of optical radiation caused by a non-thermal process [1] Luminescence is therefore a form of “cold body radiation” or “cold light,” since it does not result from heating (i e , from a relatively cool material, not above room temperature)
  • Luminescence - Laser Scientist
    Luminescence is a fascinating phenomenon where substances emit light without the need for high temperatures Unlike thermal radiation, which is light emitted due to heat, luminescence occurs at much lower temperatures, earning it the nickname “cold light ”
