1. Luminescence

   Luminescence is the spontaneous emission of light by a substance not resulting from heat; or "cold light". It is thus a form of cold-body radiation. It can be caused by chemical reactions, electrical energy, subatomic motions or stress on a crystal. This distinguishes luminescence from incandescence, which is light emitted by a substance as a result of heating. Historically, radioactivity was thought of as a form of "radio-luminescence", although it is today considered to be separate since it involves more than electromagnetic radiation. The dials, hands, scales, and signs of aviation and navigational instruments and markings are often coated with luminescent materials in a process known as "luminising".

1. luminescence

   Luminescence is the emission of light by a substance or an object that has absorbed energy or particles such as electrons. This emitted light usually has a different wavelength to the absorbed radiation. Unlike incandescence, luminescence does not require heat to produce light, thus the process occurs at low temperatures. It is a form of cold body radiation and can be seen in phenomena such as bioluminescence in living organisms, fluorescent lights, glow-in-the-dark materials, and phosphors in television screens.

Historically, radioactivity was thought of as a form of "radio-luminescence", although it is today considered to be separate since it involves more than electromagnetic radiation. The term 'luminescence' was introduced in 1888 by Eilhard Wiedemann. The dials, hands, scales and signs of aviation and navigational instruments and markings are often coated with luminescent materials in a process known as 'luminising'.

1. Luminescence

   Emission of LIGHT when ELECTRONS return to the electronic ground state from an excited state and lose the energy as PHOTONS. It is sometimes called cool light in contrast to INCANDESCENCE. LUMINESCENT MEASUREMENTS take advantage of this type of light emitted from LUMINESCENT AGENTS.
