- 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.
Fluorescence Fluorescence is the emission of light of a particular wavelength by a substance which has absorbed light of a shorter wavelength (for
