Phosphorescence definition biology
WebAug 28, 2024 · 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 process of fluorescent absorption and emission is easily illustrated by the Jablonski diagram. WebPhosphorescence is when something glows with light without becoming hot to the touch, like the glow-in-the-dark stars on your bedroom ceiling. Special paint that you can see in the dark has the quality of phosphorescence, and in nature there are certain types of plankton …
