Anotations

Scope note:

Emission of light through a means other than heat, as contrasted to light emitted from incandescent bodies, such as burning wood or molten iron. Luminescence may be seen in neon and fluorescent lamps, television, radar, in organic substances such as luminol or the luciferins in fireflies and glowworms, and in natural electrical phenomena such as lightning and the aurora borealis.
