Phosphorescence is a process whereby energy from the sun is absorbed by a '
material' and it is released slowly over a long time, in the form of light. The energy
In fluorescence, an object absorbs and releases lower energy light almost
simultaneously, but in phosphorescence, the release of light is delayed.
For the most part, prior to the nineteenth century, scientists had little concept of
light without heat. Even what premodern observers called "phosphorescence" ...
