fluorescenceShort-lived luminescence (a glow not caused by high temperature). Phosphorescence lasts a little longer. Fluorescence is used in strip and other lighting, and was developed rapidly during World War II because it was a more efficient means of illumination than the incandescent lamp.

Other important applications are in fluorescent screens for television and cathode-ray tubes. How to thank TFD for its existence?
