A trace of alkali usually increases and acid inhibits the fluorescence of solutions.
fluorescence is most efficiently excited by the cathode rays of a vacuum tube.
That is so, sir, and then we shall have the advantage of invisibility, and the enemy ships will be in fluorescence.
We must conclude that animal light is not a fluorescence of any substance due to radiation produced by the animals themselves.
Phosphorescence is exhibited chiefly by solids, fluorescence also by liquids and vapors.
The ultraviolet rays falling upon this screen were transformed into visible rays by the phenomenon of fluorescence.
Another method, which Stokes found especially useful in examining different substances for fluorescence, was as follows.
A study of riboflavin metabolism in the American roach by fluorescence microscopy.
Fluores′cent, having the property of fluorescence; Fluor′ic.
Muscarine is isomeric with betain and oxycholin, from which it is separated by its fluorescence and poisonous properties.
fluorescence fluo·res·cence (flu-rěs'əns, flô-)
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.
The property of emitting such radiation.
The emission of light from an object as a result of bombardment by other kinds of electromagnetic radiation, such as x-rays or ultraviolet rays. Fluorescent materials may appear one color when bathed in visible light and another color when exposed to other kinds of electromagnetic radiation.
Note: “Black light” depends on fluorescence for its effects.
