n.
A hydrocarbon obtained from coal-tar residues, and remarkable for its intense yellowish green fluorescence.
n.
One of the higher aromatic hydrocarbons of coal tar, allied to naphthalene and anthracene. It is a white crystalline substance, C18H12, of strong blue fluorescence, but generally colored yellow by impurities.
n.
A colorless crystalline substance, regarded as a glucoside, and found in the bark of the ash (Fraxinus) and along with esculin in the bark of the horse-chestnut. It shows a delicate fluorescence in alkaline solutions; -- called also paviin.
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 light.
n.
See Fluorescence.
n.
A complex hydrocarbon, C14H10, found in coal tar, and obtained as a white crystalline substance with a bluish fluorescence.
n.
An element of the chromium group, found in certain rare minerals, as pitchblende, uranite, etc., and reduced as a heavy, hard, nickel-white metal which is quite permanent. Its yellow oxide is used to impart to glass a delicate greenish-yellow tint which is accompanied by a strong fluorescence, and its black oxide is used as a pigment in porcelain painting. Symbol U. Atomic weight 239.
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.
a.

Changed to the epipolic condition, or that in which the phenomenon of fluorescence is presented; produced by fluorescence; as, epipolized light.
n.

a.
Producing, or relating to, epipolism or fluorescence.
n.

n.
A compound which exhibits, or from which may be prepared, a variety of colors, as certain solutions derived from vegetables, which display colors by fluorescence.
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.
n.
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.
n.
A complex nitrogenous substance related to urea and uric acid, produced as a white powder; -- so called because it forms yellow salts, and because its solution forms a blue fluorescence like quinine.
