Fluorescence :: Fluorescence (n.) That property which some transparent bodies have of producing at their surface, or within their substance, light different in color from the mass 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. The light emitted by fluorescent substances is in general of lower refrangibility than the incident l

Hydrofluosilicic :: Hydrofluosilicic (a.) Pertaining to, or denoting, a compound consisting of a double fluoride of hydrogen and silicon; silicofluoric. See Silicofluoric..

Silicofluoric :: Silicofluoric (a.) Containing, or composed of, silicon and fluorine; especially, denoting the compounds called silicofluorides..

Fluorene :: Fluorene (n.) 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..

Fluorescin :: Fluorescin (n.) A colorless, amorphous substance which is produced by the reduction of fluorescein, and from which the latter may be formed by oxidation..

Hydrofluosilicate :: Hydrofluosilicate (n.) A salt of hydrofluosilic acid; a silicofluoride. See Silicofluoride.

Thallene :: Thallene (n.) A hydrocarbon obtained from coal-tar residues, and remarkable for its intense yellowish green fluorescence..

Erythrosin :: Erythrosin (n.) A red dyestuff obtained from fluorescein by the action of iodine.

Phlogopite :: Phlogopite (n.) A kind of mica having generally a peculiar bronze-red or copperlike color and a pearly luster. It is a silicate of aluminia, with magnesia, potash, and some fluorine. It is characteristic of crystalline limestone or dolomite and serpentine. See Mica..

Phthor :: Phthor (n.) Fluorine.

Fluophosphate :: Fluophosphate (n.) A double salt of fluoric and phosphoric acids.

Silico- :: Silico- () A combining form (also used adjectively) denoting the presence of silicon or its compounds; as, silicobenzoic, silicofluoride, etc..

Uranin :: Uranin (n.) An alkaline salt of fluorescein, obtained as a brownish red substance, which is used as a dye; -- so called from the peculiar yellowish green fluorescence (resembling that of uranium glass) of its solutions. See Fluorescein..

Titano- :: Titano- () A combining form (also used adjectively) designating certain double compounds of titanium with some other elements; as, titano-cyanide, titano-fluoride, titano-silicate, etc..

Fluorine :: Fluorine (n.) A non-metallic, gaseous element, strongly acid or negative, or associated with chlorine, bromine, and iodine, in the halogen group of which it is the first member. It always occurs combined, is very active chemically, and possesses such an avidity for most elements, and silicon especially, that it can neither be prepared nor kept in glass vessels. If set free it immediately attacks the containing material, so that it was not isolated until 1886. It is a pungent, corrosive, colorles
