A plasma afterglow (also afterglow) is the radiation emitted from a plasma after the source of ionization is removed.The external electromagnetic fields that sustained the plasma glow are absent or insufficient to maintain the discharge in the afterglow. A plasma afterglow can either be a temporal, due to an interrupted (pulsed) plasma source, or spatial, due to a distant plasma source. In the afterglow, plasma-generated species de-excite and participate in secondary chemical reactions that tend to form stable species. Depending on the gas composition, super-elastic collisions may continue to sustain the plasma in the afterglow for a while by releasing the energy stored in rovibronic degrees of freedom of the atoms and molecules of the plasma. Especially in molecular gases, the plasma chem

| - 餘輝電漿(Afterglow plasma)是指當電漿受到外來的電磁場影響而發光(未必可見)，而當電磁場消失導致電漿無法持續發光時，電漿發出的殘光。一般電漿餘暉都不持久，但電漿會以釋放能量的方式來延長餘輝電漿的電時間，此效果在分子氣體裡特明顯。 (zh)

| - A plasma afterglow (also afterglow) is the radiation emitted from a plasma after the source of ionization is removed.The external electromagnetic fields that sustained the plasma glow are absent or insufficient to maintain the discharge in the afterglow. A plasma afterglow can either be a temporal, due to an interrupted (pulsed) plasma source, or spatial, due to a distant plasma source.

Depending on the gas composition, super-elastic collisions may continue to sustain the plasma in the afterglow for a while by releasing the energy stored in rovibronic degrees of freedom of the atoms and molecules of the plasma. Especially in molecular gases, the plasma chemistry in the afterglow is significantly different from the plasma glow. The afterglow of a plasma is still a plasma and as thus retains most of the properties of a plasma. (en)
