Luminescence is the emission of light from a substance through chemical reactions or exposure to energy like ultraviolet light, rather than from heat alone. It matters because it has practical applications in areas like forensic science (detecting blood at crime scenes) and medical diagnostics (identifying microorganisms).

Luminescence is the emission of optical radiation (ultraviolet, visible, or infrared) by a substance due to a process other than heating. In the broad chemical/photochemical sense, luminescence is the spontaneous emission of radiation from an electronically or vibrationally excited species that is not in thermal equilibrium with its environment.
