磷光 Phosphorescence

（重定向自Phosphoresce）
具有磷光性的粉末分别处于可见光下、紫外线下和完全黑暗的环境中
由磷光构成的鸟形

磷光是一种缓慢发光的光致发光现象。当某种常温物质经某种波长的入射光（通常是紫外线或X射线）照射，吸收光能后进入激发态（通常具有和基态不同的自旋多重度），然后缓慢地退激发并发出比入射光的的波长长的出射光（通常波长在可见光波段），而且与荧光过程不同，当入射光停止后，发光现象持续存在，其衰退时间大于 10^{-8} 秒。发出磷光的退激发过程是被量子力学的跃迁选择规则禁戒的，因此这个过程很缓慢。

Phosphorescence 磷光

（重定向自Phosphoresce）
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.
