Abstract
Luminescence denotes the emission of radiation by a solid in excess of the amount emitted in thermal equilibrium and can be considered as a process inverse to the absorption of radiation. Since luminescence is basically a non-equilibrium phenomena, it requires excitation by light, electron beams, current injection, etc., which generally act to create excess electrons, holes, or both. For example, the effects of electron–hole recombination give rise to recombination radiation or luminescence.
