Fluorescence was observed long before it was named and understood. An early observation of fluorescence was known to the Aztecs and described in 1560 by Bernardino de Sahagún See more

There are several general rules that deal with fluorescence. Each of the following rules have exceptions but they are useful guidelines for understanding fluorescence (these rules do not necessarily apply to two-photon absorption).
Kasha's rule See more

There are many natural compounds that exhibit fluorescence, and they have a number of applications. Some deep-sea animals, such as the See more
