Luminescence is a spontaneous emission of radiation from an electronically or vibrationally excited species not in thermal equilibrium with its environment. A luminescent object emits cold light in contrast to incandescence, where an object only emits light after heating.
Luminescence is the emission of light by certain materials when they are relatively cool, in contrast to incandescence. Learn about the sources, processes, and applications of luminescence, as well as its history and types, such as fluorescence, phosphorescence, and chemiluminescence.
