Definitions and meanings of "Fluorescence"

What do we mean by fluorescence?

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. 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. 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. noun

The emission of light (or other electromagnetic radiation) by a material when stimulated by the absorption of radiation or of a subatomic particle noun

The light so emitted noun

Light emitted during absorption of radiation of some other (invisible) wavelength noun

The emission of light (or other electromagnetic radiation) by a material when stimulated by the absorption of radiation or of a subatomic particle.

The light so emitted.
