Phosphorescent Ink
Ink containing components which emit light after exposure to light of a specific wavelength (normal light or UV light). In phosphorescent materials the emission of light continues after cessation of the stimulated radiation (from 10-8 seconds to several seconds or hours) whereas fluorescence is a very short-lived emission which ceases within 10-8 seconds (fluorescent ink).
