A fluorescent substance absorbs short wavelength radiation and re-emits it as radiation with a longer wavelength in a very short time.

Property exhibited in certain minerals in which they display a glowing effect when having ample illumination with ultraviolet light. See Fluorescence in Mineral Properties for more information.

emission of light by a substance during exposure to another source of light.

The emission of light by an excited molecule in the process of making the transition from the excited state to the ground state.

A property of a mineral to glow with certain colors when exposed to an ultraviolet light.

The property of a substance, such as the mineral fluorite, of producing visible light while it is being acted upon by ultraviolet light.

Light resulting from the action of ultraviolet or other forms of energy on phosphors. Fluorescence occurs only while energy is being absorbed by the fluorescing material.

The emission of light during the absorption of radiation from another source.

luminescence arising from irradiation with light

glow of light from a substance exposed to ultraviolet radiation. The atoms de-excite in stages and emit visible photons

(n) light emitted during absorption of radiation of some other (invisible) wavelength

Fluorescence is the absorption and subsequent emission of light of two different frequencies, or wavelengths. This is typically seen in experimental setups when a lower wavelength band of incident light is absorbed from one direction, and a higher wavelength band of light is emitted in all directions. This is most striking when a sample absorbs ult [..]

the absorption of a certain wavelength (or color) of light and the re-emission of that light at a longer wavelength (a different color)

— a process by which substances give off light or another form of electromagnetic radiation when they absorb energy.

Property of emitting light as the result of, and only during the absorption of radiation from some other energy source.

The emission of light energy by a substance as a result of the absorption of energy from ultraviolet radiation.

Fluorescence is a process in which substances are excited by means of radiation to produce light; the wavelength of the emitted light is always higher than the wavelength of the incident radiation. On [..]

A neon-like glow that's radiated by some substances when exposed to ultra-violet light.

The property of emitting Radiation while being irradiated. The Radiation emitted is usually of longer wavelength than that incident or absorbed, e.g., a substance can be irradiated with invisible Radi [..]

If a substance absorbs light at one wavelength and re-radiates it at another wavelength almost immediately, it is fluorescent; this is why many materials glow under ultraviolet light. If the substance keeps re-radiating light over a period of seconds, minutes, or hours, it is called phosphorescent.

The phenomenon of emitting light upon absorbing radiation of an invisible wavelength.

The emission of electromagnetic radiation following absorption of shorter wave length light.

The emission of visible light by a substance exposed to ultraviolet (UV) light. Some materials, when exposed to invisible UV radiation, emit visible light and seem to "glow-in-the-dark.&q [..]

Property of certain minerals in which it displays a multicolored effect when having ample illumination with ultraviolet light.(See Fluorescence in mineral properties for more information)

Fluorescence is an optical property associated with many gemstones. It occurs when various forms of electromagnetic energy (ultraviolet light, infrared light, or x-rays, for example) are absorbed by the host material, and some portion is re-emitted in the visible-light spectrum. Fluorescence is often used as a diagnostic tool when identifying gemst [..]

Emission of light or other radiant energy as a result of and only during absorption of radiation from some other source.

Emission of light by excited molecules as they revert to the ground state.

Excitation light energy is absorbed by fluorescent molecule, the molecule transitions to an excited state and as it returns to unexcited ground-state, a specific wavelength of light is emitted.

Emission of secondary light generated by excitation by ultraviolet light, a beta particle or a gamma ray.

the absorption of energy by atoms, molecules, and other particles, followed by the immediate emission of visible electromagnetic radiation as the particles move to lower energy states

A property of Fluorescent dyes, also called optical brightness which often added to paper to enhance paper's whiteness or brightness to the eye in normal lighting.

property of many substances, of absorbing light of one wavelength (or colour) and emitting light of another wavelength (or colour).

The emission of light by a substance that has absorbed light or other electromagnetic radiation. The absorbed and emitted light are usually different wavelengths and therefore produce different colors [..]
