fluorescencija

fluorescencija

The emission of electromagnetic radiation as the result of exposure to some other radiation, which emission ceases when the stimulus that produces it ceases to act on the emitting substance. Thus light passing through a gas, may change the energy state of the atoms and cause them to emit light of a different wavelength.
