Phosphorescence

Jablonski diagram of an energy scheme used to explain the difference between fluorescence and phosphorescence. The excitation of molecule A to its singlet excited state (1A*)is followed by intersystem crossing to the triplet state (3A) that relaxes to the ground state by phosphorescence.
After an electron absorbs a photon of high energy, it may undergo vibrational relaxations and intersystem crossing to another spin state.  Again the system relaxes vibrationally in the new spin state and eventually emits light by phosphorescence.
Phosphorescence of the quartz ignition tube of an air-gap flash

Phosphorescence is a specific type of photoluminescence related to fluorescence. Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs. The slower time scales of the re-emission are associated with "forbidden" energy state transitions in quantum mechanics. As these transitions occur very slowly in certain materials, absorbed radiation may be re-emitted at a lower intensity for up to several hours after the original excitation.
