When a substance emits visible light when exposed to light of a shorter wavelength. Ultraviolet light, for example, will cause many objects to fluoresce.
Emits light while exposed to light.
A process in which a compound emits light at one wavelength while being excited by radiation with a shorter wavelength.
the emission of light by a substance.
Produce light when exposed to radiation of a particular wavelength. For example, some substances fluoresce when exposed to ultraviolet light.
exhibit or undergo fluorescence - which is light emitted during absorption of radiation of some other (invisible) wavelength.
