luminescence    音标拼音: [l,umən'ɛsəns]
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]

  • Decoding Luminescence Vs Fluorescence - Smore Science
    Luminescence and fluorescence are types of light emission that occur in certain materials While interesting, they are relatively straightforward physical phenomena with well-understood mechanisms in modern physics The essence of luminescence is that substances emit light without being heated
  • Luminescence, fluorescence, and phosphorescence - Explain that Stuff
    That's an example of what we call photoluminescence: luminescence made by light But you can make things give off light by exciting their atoms with many other kinds of energy You give the atoms one kind of energy (light, heat, sound, or whatever) and they give the same energy back to you as light

  • What is luminescence and its types? - ScienceOxygen
    Luminescence is the phenomenon involving absorption of light at a specific wavelength by a chemical molecule (the excitation wavelength) and the emission of light at a longer wavelength (the emission wavelength)
  • Luminiscence Type - an overview | ScienceDirect Topics
    Luminescent refers to a property of materials that emit (near)-visible light as a result of energy conversion, often initiated by electromagnetic radiation, electrical, or chemical excitation, which energizes the atoms and causes them to release excess energy in the form of electromagnetic radiation
