  • Things that Excite ElectronsLight examples:Fluorescence - A photon creates a very brief excited state (10-9 to 10-6 seconds) then when the electron returns to the ground state a different type of photon is released.

    Phosphorescence - A photon creates longer excited state (10-3 to several minutes).

    Glowing Bones and other glow things

  • Fluorescence: Photographed with a black light

  • South Korean scientists tinkering with fluorescence protein genes say they have bred white Turkish Angora cats to glow red under ultraviolet light. Fluorescence: Photographed with a black light

  • Things that Excite ElectronsNuclear Reaction examples:Radioactive Decay

  • Radium mixed with copper-doped zinc sulfide produces a paint that will glow in the dark. The radiation from the decaying radium excites electrons in the doped zinc sulfide to a higher energy level. When the electrons returned to the lower energy level, a visible photon was emitted.

  • Actinium is a silvery radioactive element that glows pale blue in the dark.

  • This is a photo of uranium glass, which is a glass to which uranium was added as a colorant. Uranium glass fluoresces bright green under a black or ultraviolet light.

  • The night sights on some guns and other weapons use radioactive tritium-based paint. The electrons emitted as the tritium decays interact with the phospor paint, producing a bright greenish light.

  • Nuclear reactors display a characteristic blue glow because of Cherenkov radiation, which is a type of electromagnetic radiation that is emitted when a charged particle moves through a dielectric medium faster than the phase velocity of light. The molecules of the medium are polarized, emitting radiation as they return to their ground state.

  • Spent fuel rods in a holding pool.
