A fluorescent material glows much brighter than typical colors. See beautiful examples of fluorescence and learn how this natural phenomenon works.

Video Summary

Fluorescence occurs when an electron is pushed into in a higher orbit (higher energy state). When the electron returns to its normal energy ground state, it emits excess energy as a photon, typically of visible light. A UV light can cause this to happen if shone on fluorescent materials. Fluorescent materials fluoresce various colors, for example uranium glass shines green. Fluorescent materials are used in safety clothing, light bulbs, and most computer/TV screens.
