Fluorescence

ahd-5
  • noun. The emission of electromagnetic radiation, especially of visible light, stimulated in a substance by the absorption of incident radiation and persisting only as long as the stimulating radiation is continued.
  • noun. The property of emitting such radiation.
  • noun. The radiation so emitted.
    • The Century Dictionary and Cyclopedia
  • noun. The property possessed by some transparent substances of becoming self-luminous while they are exposed to the direct action of light-rays. See phosphorescence.
    • the GNU version of the Collaborative International Dictionary of English
  • noun. A luminescence emitted by certain substances due to the absorption of radiation at one wavelength, and the almost instantaneous re-emission of radiation at another, usually longer wavelength. The re-radiation stops almost as soon as the incident radiation is halted, thus distinguishing this phenomenon from phosphorescence, in which re-radiation of light may continue for some time after the incident radiation is halted.
