What Is Luminescent Light?

Luminescence is the emission of light produced by methods other than heat. Luminescence is caused by the movement of electrons into different energetic states. There are many different types of luminescence including bioluminescence, chemiluminescence, phosphorescence, and fluorescence.

What is luminescent light for kids?

Luminescence is light emitted by a substance not caused by heat. In contrast, incandescence is light emitted by a substance as a result of heating. Luminescence can be caused by chemical reactions, electrical energy, subatomic motions, or piezoelectricity (stress on a crystal).

What is luminescent used for?

Major applications are in emissive displays, fluorescent lamps and LEDs and systems to detect X-rays or γ-rays, for example, used in medical imaging. In the latter kind of applications, luminescent materials are excited by photons with high energy, and part of the excitation energy is used to create visible light.
