Definition of fluorescence

i. The emission of visible light by a substance exposed to ultraviolet light. It is a useful property in examining well cuttings for oil shows and in prospecting for some minerals.

Ref: AGI

ii. The absorption of radiation at one wavelength, or a range of wavelengths, and its reemission as radiation of longer, visible wavelengths.

iii. A type of luminescence in which the emission of light ceases when the external stimulus ceases; also, the light so produced.

Ref: AGI

iv. Quantized electromagnetic radiation as a material drops from a higher to a lower energy state. Fluorescence stops when the excitation energy stops.

Compare with: phosphorescence, luminescence
