Fluor

‖n. [ L., a flowing, fr. fluere to flow. See Fluent. ] 1. A fluid state. [ Obs. ] Sir I. Newton. [ 1913 Webster ]

2. Menstrual flux; catamenia; menses. [ Obs. ] [ 1913 Webster ]

3. (Min.) See Fluorite. [ 1913 Webster ]

Fluor albus

‖ [ L., white flow. ] (Med.) The whites; leucorrhæa. [ 1913 Webster ]

Fluoranthene

n. [ Fluorene + anthracene. ] (Chem.) A white crystalline hydrocarbon C15H10, of a complex structure, found as one ingredient of the higher boiling portion of coal tar. [ 1913 Webster ]

Fluorated

a. (Chem.) Combined with fluorine; subjected to the action of fluoride. [ R. ] [ 1913 Webster ]

Fluorene

n. (Chem.) A colorless, crystalline hydrocarbon, C13H10 having a beautiful violet fluorescence; whence its name. It occurs in the higher boiling products of coal tar, and is obtained artificially. [ 1913 Webster ]

fluorescein

n. (Chem.) A yellowish red, crystalline substance, C20H12O5, produced by heating together phthalic anhydride and resorcin; -- so called, from the very brilliant yellowish green fluorescence of its alkaline solutions. It has acid properties, and its salts of the alkalies are known to the trade under the name of uranin.
Syn. -- fluorescein, fluorescent dye, resorcinolphthalein. [ 1913 Webster ]

Variants: fluoresceine
Fluorescence

n. [ From Fluor. ] (Chemistry, Optics) 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. The color of the radiated light typically differs from the apparent color of the material, as when green crystals of fluor spar afford blue reflections. It is due not to the difference in the color of a distinct surface layer, but to the power which the substance has of modifying the light incident upon it, by first absorbing the light to achieve an excited state, and then radiating light to resume the ground energy level. The light emitted by fluorescent substances is in general of longer wavelength than the incident light. The radiation can also be induced by ionizing radiation which is not electromagnetic, such as alpha or beta rays, and cathode rays. This property is possessed by fluorspar, uranium glass, sulphide of calcium, and many other substances. It finds use in analytical instruments to detect or measure radiation, and in some commercial applications. [ 1913 Webster +PJC ]

Fluorescent

a. Having the property of fluorescence. [ 1913 Webster ]

Fluorescin

n. (Chem.) A colorless, amorphous substance which is produced by the reduction of fluoresceïn, and from which the latter may be formed by oxidation. [ 1913 Webster ]

Fluoric

a. [ Cf. F. fluorique. ] (Chem.) Pertaining to, obtained from, or containing, fluorine. [ 1913 Webster ]
