La luminescence est la propriété que possèdent quelques corps d'émettre des rayons lumineux quand on les soumet à certaines actions physiques. Cette luminescence se subdivise en fluorescence si l'émission cesse avec la cause qui la produit et en phosphorescence si elle persiste plus ou moins longtemps. 1, record 1, French, - fluorescence

«fluorescence» : Ce stockage [d'énergie] [...] se termine par la réémission, dans une direction quelconque, d'un photon de même énergie que le premier. C'est ce que l'on appelle l'émission «spontanée» (ou fluorescence). 2, record 2, French, - %C3%A9mission%20spontan%C3%A9e

«fluorescence» : Orszag semble un des seuls auteurs à employer «fluorescence» comme synonyme d'émission spontanée. «Fluorescence» est moins courant dans ce sens et risquerait de créer une ambiguïté avec le sens le plus courant utilisé en physique. 5, record 2, French, - %C3%A9mission%20spontan%C3%A9e
